1990 teg won't stay started

[Tatsu]

My 1990 integra will only start with the gas pedal to the floor and when you let of the gas it dies out. but when it is started with the gas pedal to the floor it backfires load but only one time. The plugs and wires are new and i just put at new timming belt on it. What else could it be?

[C25A1guy]

are the wires in the cap in the correct firing order?

[Tatsu]

yes they are but i will check again. what else could it be?

[Tatsu]

They are the way the hayens repair manully said

sounds like ur timing is off, get ur number 1 cylinder to top dead center and check to see if the timing mark on the cam gear is lined up to where it should be

[Tatsu]

i did it but did not have a timming light. i just put a new belt on it yesterday. so what else could it be?

[C25A1guy]

You don't really need a timing light for this. hand crank the engine til #1 is at TDC, remove the valve cover and check your cam timing. on the sprockets should be little arrows and they should more or less be pointing at each other (if I remember correctly).

u might be wrong, on my 92' the sprockets said UP on them and i had to put both ups, up...obviously lol

but yeah also do what C25A1guy said, make sure ur plugs are in right firing order

Timing and electrical components of the ignition system seem to be the most likely culprits. Check the resistance in the plug wires, check the plugs for wear. Look at the cap and the rotor and see if they are worn. Check the ignition coil for the appropriate resistance between the appropriate terminals. Borrow a timing light from someone or just buy a cheap one and make sure that your spot on. It can be easy to get the timing 180 degrees off too. Something to check.

Throw in my .02, I agree its timing.

Either your belt skipped or the install was done wrong on the belt. If everything checks out then I would look at the TPS.

i dont think it will be his TPS, when i dropped the motor into my 92' i busted the plug right off my TPS and i was still able to drive my car, it just had a major lack of power when starting from a dead stop...

get number 1 cylinder top dead center, pull off ur distributor cap and the rotor should be pointing to ur number 1 plug, number 1 plug is is on bottom back of dizzy cap(if ur standing directly in front of ur car)

A bad TPS can make your engine stall and since its a common issue on integras it can't be ruled out by simply stating that you disconnected it and it didn't stall. When you disconnect a sensor your ECU goes into a fail safe mode so it will use its fail safe mode to keep the car going in some cases. a faulty sensor sending the wrong or bad signal however can make the cars ECU become confused and mix air and fuel wrong and add too much fuel not enough air or visa versa.

Timing is more likely like I said but don't be so quick to discount the TPS

Autozone says there is no tps on the 1990 integra and they say that it is not needed. could it be the o2 sensor? the Haynes Manul said it could be the o2 sensor.

thats cause autozone are idiots they said the same thing to me....but they "think" it dont have 1 cause when they look it up on their computers it dont show up cause its dealer only part.....acura dealers charge and arm and both legs for a TPS, when i needed one i went to acura and they wanted $550 for 1.

theres sites online u can get TPS for like $75 or u can take the chances of buying 1 from a junkyard but i think they will only let u buy the entire throttle body. and it dont really matter what the TPS comes off of as long as u dont take 1 off a V-tec motor and try to use it on a non V-tec.

u can take 1 from a civic and use on ur integra, i took 1 off a 98 civic motor in my garage and it worked fine on my 92' integra motor, dont use TPS off anything older then a 90...i believe most 89 and older cars TPS wont work

also TPS is a pain to take off, i had to grind a flat line across the screw/bolt things and use a flat head screwdriver to take em out

[Tatsu]

ok thanks. the ecu is showing that it is a bad o2 sensor if so could that just be the problem?
