nissan4x4 Posted November 14, 2007 Share Posted November 14, 2007 we first thought it was a distributor, but today i replaced the distributor with one from ebay and still nothing just turns over no fire is there some kind of fuse to replace or what im lost Link to comment Share on other sites More sharing options...

revgolem Posted November 15, 2007 Share Posted November 15, 2007 Dont know what tools you have so ill give you the quick and dirty way to narrow it down. pull the easiest plug and hold slightly away from a ground while someone turns it over (might want to use an insulated tool, but it wont kill you) got spark? pull fuel line off of the filter and turn on the key (dont have to try to start it). if you dont see a puddle of fuel then the pump is bad. if its turning over at a descent speed that it probobly isint the starter. give it a go and see where it takes you... not a whole lot to go on but its a start.

k9sar Posted November 15, 2007 Share Posted November 15, 2007 basic internal combustion engine operation: Needs air Needs fuel Needs fire Needs them all at the right time start easy... check air filter, if completely clogged, replace. Temporarily remove and see if it tries to start Pull a plug (number 1 would be a good choice). Look at the electrode. Is it wet with gas? If not, you have a fuel problem. The only time it should be dry is if the engine is running or has recently run and is still warm. Cranking it over without starting should get fuel in the cylinders. While the plug is out, lay the base against a good ground point and crank it over. Should see a nice bright spark to the electrode. If it dim/orange/weak, the problem may be the plug or the coil. If you have air, fuel and fire, now check your timing. Pop the dist cap and look at the position of the rotor in relation to the location of plug wire 1. Carefully insert a long screwdriver or chopstick into the plug 1 hole. Crank the engine by hand until the indicator (stick or screwdriver) is at the topmost travel. Your rotor should be at or just past either the number 1 spot or off 180 degrees. Link to comment Share on other sites More sharing options...
nissan4x4 Posted November 15, 2007 Author Share Posted November 15, 2007 were still getting no spark its a new distributor i put in, is there some kind of fuse to keep power from the distributor. Link to comment Share on other sites More sharing options...
Simon Posted November 15, 2007 Share Posted November 15, 2007 Nope...but are you getting spark from the coil? Check that first. If the coil isn't firing, you won't get spark to/from the distributor. There's a little grey box behind the ignition coil that I believe is the coil "amplifier" Make sure the connections to it are snug/clean as well.

unccpathfinder Posted November 15, 2007 Share Posted November 15, 2007 I have an almost new coil (and an older coil that was still good but got replaced while trouble shooting) and the resistor pack these guys are speaking of if you need one for a decent price compared to the new price...shoot me a PM if so Link to comment Share on other sites More sharing options...
nissan4x4 Posted November 16, 2007 Author Share Posted November 16, 2007 where is the coil located also i saw this red capped wire coming from the cap and going to this black rectangler box whatis it. Link to comment Share on other sites More sharing options...
unccpathfinder Posted November 16, 2007 Share Posted November 16, 2007 (edited) hang on lemmie get a pic of the resistor/coil and its on your driver side fender well...I'll have to search to see if I have any pix... Ok so waht I think you described is the coil wire...Find the wire marked C of the dist cap...follow it over to the driver side fedner well...and waht it connects to is the coil...and what the coil connects to is the resistor...see attached pix...

nissan4x4 Posted November 16, 2007 Author Share Posted November 16, 2007 (edited) thats it, but how do i check it ,and should it be replaced could it be causing this if it went out. Edited November 16, 2007 by nissan4x4 Link to comment Share on other sites More sharing options...
unccpathfinder Posted November 16, 2007 Share Posted November 16, 2007 I think you can check the resistivity? Link to comment Share on other sites More sharing options...
nissan4x4 Posted November 16, 2007 Author Share Posted November 16, 2007 how do you do that Link to comment Share on other sites More sharing options...
k9sar Posted November 16, 2007 Share Posted November 16, 2007 with a resistivity meter bwahaahaaa an Ohm meter. Link to comment Share on other sites More sharing options...
nissan4x4 Posted November 16, 2007 Author Share Posted November 16, 2007 (edited) where do you check it at an to test it does the truck have to turn over or just be on Edited November 16, 2007 by nissan4x4 Link to comment Share on other sites More sharing options...
nissan4x4 Posted November 17, 2007 Author Share Posted November 17, 2007 i replaced the distributor and the coil new spark plugs too and the pathy still does not start all i get is a weak orange spark and it does not start i dont know what else i can replace.

zonianbrat Posted November 17, 2007 Share Posted November 17, 2007 Have you checked fuel delivery? Fuel filter, Fuel pump? Link to comment Share on other sites More sharing options...

unccpathfinder Posted November 17, 2007 Share Posted November 17, 2007 (edited) hope that helps... did you check for codes...you may have a bad Crank angle sensor (i've got one of those too I can sell...well the whole dizzy) Edited November 17, 2007 by unccpathfinder Link to comment Share on other sites More sharing options...
nissan4x4 Posted November 18, 2007 Author Share Posted November 18, 2007 well i replaced the whole distributor so i dont think the crank angle sensor is off this information will help Link to comment Share on other sites More sharing options...
nissan4x4 Posted November 18, 2007 Author Share Posted November 18, 2007 we got fuel we smell it and the sparkplugs have gas on them but we have a weak light orange spark and the truck turns over but never starts. Link to comment Share on other sites More sharing options...
94extreme Posted November 18, 2007 Share Posted November 18, 2007 the sparkplugs have gas on them clean and dry them thoroughly.. let the cylinders "breath out" the gas.. it'll never start with plugs soaked in gas. Link to comment Share on other sites More sharing options...
94extreme Posted November 18, 2007 Share Posted November 18, 2007 well i replaced the whole distributor so i dont think the crank angle sensor is off this information will help check the codes anyway as you never know. Link to comment Share on other sites More sharing options...
nissan4x4 Posted November 18, 2007 Author Share Posted November 18, 2007 there not soaked in gas but when it turns over you can smell gas out the tail pipe raw gas Link to comment Share on other sites More sharing options...
k9sar Posted November 18, 2007 Share Posted November 18, 2007 check the resistance of your coil wire. Too high and that will inhibit good spark. It's quite possible that the metal clippy thing inside the boot has broken away from the wire core and you do not have good contact. I think you have pretty much narrowed it down to the spark. When you got your weak spark, was it on a plug connected to a plug wire? You can pop a plug directly on the coil wire (take the distributer completely out of the diagnostic loop) and check again. If that is weak, you might consider swapping your coil wire with the plug wire that you already pulled and see if you get good spark through that wire (coil - through sparkplug wire - to plug grounded on block. if you don't use a plug to check, you can put a screwdriver in and hold the edge near a ground point. Spark should easily jump a quarter inch or so. careful though... they can bite. Link to comment Share on other sites More sharing options...
