GhostPath Posted February 8, 2008 Share Posted February 8, 2008 Do you have spark at all? The computer controls the injectors and the ignition and if it can't tell what position the crank or distributor are in it won't fire either. Link to comment Share on other sites More sharing options...
ricecrusher Posted February 10, 2008 Author Share Posted February 10, 2008 ya has great spark, is there a crank angle sensor on the older VGs? Link to comment Share on other sites More sharing options...
jj big shoe Posted February 10, 2008 Share Posted February 10, 2008 Yes, its part of the distributor. Try running the trouble codes stored in the ECU. Here's the link on how to do it and what the codes mean. Let us know... Link to comment Share on other sites More sharing options...
88pathoffroad Posted February 11, 2008 Share Posted February 11, 2008 Yup, run the ECU error codes first. Link to comment Share on other sites More sharing options...
ricecrusher Posted February 12, 2008 Author Share Posted February 12, 2008 Did that long time ago no codes Link to comment Share on other sites More sharing options...
88pathoffroad Posted February 14, 2008 Share Posted February 14, 2008 Try it again now? Who knows... You can also test the resistance of the injectors, it should be pretty low, like 4 ohms IIRC. If it's high on both then you'll probably need new injectors. Link to comment Share on other sites More sharing options...
ricecrusher Posted February 14, 2008 Author Share Posted February 14, 2008 Swapped throttle bodys 3 times still nothing we are starting to think its a wireing problem. Link to comment Share on other sites More sharing options...
