I Have a 89 hatch with the stock motor. Sometimes when im driving the check engine light comes on and it idles real high then sometimes when i go to try and start the car the light comes on and the car wont start. If i leave it alone and come back later it starts right up with no problem. I took off the lines to the fuel filter and it doesnt get fuel when the check engine comes on. Im thinking a bad fuel relay? but im not sure.

 

Um...have you bothered to pull the code? Start there.....

 

no i dont have anything to do it with

 

yea you do...you can count right?

 

i know how to do it now, Where is the plug on my car? is it under the glove box?

 

there is no plug on your car thats for obd1 and up, you just have to pull up your passenger carpet and look through the little window on the ecu and count how many times the red led flashes after you turn the key to the on position

ok well it threw a 16 then 17 then i pulled the hazard fuse for 10 seconds and the 17 went away (my speedometer didnt work for like a month) so im gonna check my grounds tomm then go buy a new injector. Thanks

 

if my car only has one fuel injector would it be known as the "TBI" injector (throttle body injector) the other ones i see online all say 4 per car and i only have one

 

well if you have dpfi, you have 2 fuel injectors a main and auxilary, try new fuel injectors, i have an old dpfi manifold with the injectors still in it if it comes down to that
