bigfisch1191 Posted November 29, 2007 Share Posted November 29, 2007 (edited) Ok so today I went outside started up my truck let it warm up and drove it a few blocks down the road on my way to school, when all of a sudden the tack started freaking out going from the red zone to no rpms at all, but the motor was running normal, so I was like what the hell. I stopped at the stop sign and hit the gas and at that point the tack was at 0 rpms and then the motor started losing power and jumping little and then it died so I put it in neutral and coasted to the next stop sign and tried to start it. It was turning the motor over and but not starting, for like a min (and yes I put it in park) then it started and was barley idling at 300 rpm and then I gave it gas and it died. I got it to start again and it was barley dialing and I gave it gas slowly and it started to climb and it was fine and so was the tack so I continued and then it did the same thing as before tack stared jumping and it died. So I finely got it home like that and parked it have been trying to find out what’s wrong, on this site and by checking out the truck. But cant find anything. And now it won’t even start. Last 4x4 outing was last weekend on sat, went threw a mud/water pit that went over my hood thought I might have sucked water into the engine but drove home fine. Vehicle info 1988 4x4 3.0 liter v6 auto I don’t really know what to do I was thinking it might be the tack that went bad and the ECU takes info from that and is just making the engine die I don’t know any help would be apreciated no mater how crazy it sounds.

88pathoffroad Posted December 1, 2007 Share Posted December 1, 2007 The tach does not affect engine performance or operation in any way. You have a problem elsewhere...did you check your air filter after getting it wet? The procedure for checking your ECU error codes is posted in the Garage How-To section...

95shakinPF Posted December 1, 2007 Share Posted December 1, 2007 Flooded the distributor maybe? Or coil has corroded up after drying!??! Link to comment Share on other sites More sharing options...
SnakeS Posted December 1, 2007 Share Posted December 1, 2007 yes the tach takes the reading from the distributer so if they are both in tandem then they're might be water inside the cap or sumthin Link to comment Share on other sites More sharing options...
yozsi Posted December 1, 2007 Share Posted December 1, 2007 cmon guys..... its the icm going bad. the ignition module is bad, id bet thats the problem. Link to comment Share on other sites More sharing options...
bigfisch1191 Posted December 1, 2007 Author Share Posted December 1, 2007 the only thing is i drove it for 3-4 days with no problems after i went threw the water. but its not getting spark at the coil so i dont think its the distributer i need to get out there with a test light and check were it is getting power.

88pathoffroad Posted December 2, 2007 Share Posted December 2, 2007 The power transistor on the coil can go bad, but they're sealed so I doubt a dunking will kill one. Check the wiring connectors for corrosion or looseness? Link to comment Share on other sites More sharing options...
bigfisch1191 Posted December 4, 2007 Author Share Posted December 4, 2007 put a new coil on it it did jack nothing Link to comment Share on other sites More sharing options...
cohen Posted December 5, 2007 Share Posted December 5, 2007 wow total deja vu'!! I had the exact same problem about a month ago, its the crankshaft position angle sensor inside the distributor the only way to fix it is to replace the whole distributor. I sat on it for a little less then a month and listened to everyone telling me to check codes and try this and try that and nothing worked untill I changed the distributor and I haven't had any problems since Link to comment Share on other sites More sharing options...
94extreme Posted December 5, 2007 Share Posted December 5, 2007 the code light comes on but does not blink. somehow i missed this before.. what do you mean by that?.. it has to blink something. even an 'all clear' code.. did you check the how-to's for error code recovery?

bigfisch1191 Posted December 12, 2007 Author Share Posted December 12, 2007 cmon guys..... its the icm going bad. the ignition module is bad, id bet thats the problem. yozsi got it right, it was the ignition control module, i went to a local shop and told them the symtomes and they said that is were i should start. so i checked the price on one and it was like 150$, so i went to a u-pull-it and got the icm and coil for 50$(+a ton of other pathy godies). then it took 15 sec to put it in and the pathy started up like a champ.
