My friend is working on a 92 Tracker and cant get it to run. He is getting fire and fuel to the motor but no injector pulse. Any ideas of what could be wrong?

Thanks Zig

I hate to say this but I think it's probly one of 2 places

- Poor connection or somehting hooked up wrong
- ECU

Typically no injector pulse from my experience is ECU

Best guess...

Cooll thatnks Zag, that was Mikes conclusion too. I will let Jimmy know.

Zig, also when the key is in the on pos there should be 12V on one side ov the inj. conn. If there isn't you have a powefeed prob. and check the feed ckt.

Thanks Zig

you cant have one without the other.

had the same prob a couple of months ago on my nissan truck, took my mechanic 2 weeks to trouble shoot it cause everytime he would put the scanner on it it would fire up again(really messed with him)ended up being a corroded plug at the batt terminal that was the main power for the computer. had fuel press at the rail, had spark, would run when i would dump fuel into the air body.
look at those plugs, might be the problem

I had the same problem with my X when I did the swap,

I was getting fuel, fire, ignition, compression, detonation but no combustion?.....

Wait, that was a bad dream... nvm
