Ecu's 1994-1995

[Lunartic]

I have an intermettent starting problem when starting the 95, but only once in a while. See when I start it I go to rev it a bit and it feels like its running on 4-5 cyls. I then turn off the key and start it again. Sometimes it starts properly and sometimes it starts like crap. Usually lately when I start it i have been reving it up just a bit to see how it runs. If it spurts like i was saying, I'll try again until it clears itself. What the HECK is going on with my truck.

I got a used ECU from a 1994 pathy and was wondering if that my be the problem and was wondering if they are generic between the two years 1994-1995, cause they sure look the same.

Thanks guys.

Regards.

Check your ECU error codes first. I think the two will interchange.

sounds like it's starving for fuel..... does it run ok once you get going?

[Lunartic]

Yes. It run's like a charm when it's going right. But if not it will kinda smell of rotten fuel. Sometimes it takes 2/3 starts to correct it. There is no error codes coming up on the ECU when it runs like that.

You could always try cleaning the MAF sensor if you haven't lately. Does it smell like rotten eggs after going up a hill or after being on the freeway?

Hi guys. She ran like a charm 2day after starting it 3 times or more ... Each way to work. But dunno. I've changed tb sensor, cleaned map sensor, changed 02 sensor, cleaned intake, plugs, filters (them all) yadda, yadda, yadda. 360000k shes still strong and getting rubber down but thats after I get it to run good. What eother sensor? I've gone over them all i think. If it was the gas pump would it not have quit like 20000 or so back when this crap started? Wondering?
