Starting Problems
 

Ok, I am new, and i just bought an 87 supra turbo, 2 weeks ago. I have searched on this forum, for help with my problem, but cant find anything that quite fits me. Anyway everytime i start the car, when the engine is cold or warm(when the car is already hot, no problem). It takes awhile to start, sometimes up to 5 mins. Because when it does catch, it might stall out. Then when the engine wants to keep running, it runs kind of rough, like it is about to stall. So once I have let is warm up some. I try to put it in drive or reverse, sometimes the engine will run for about 2 seconds then stall. Once the car is in motion, and is hot(not overheating hot) , the car runs great. The guy i bought is from said the timing needed to be ajusted, but i dont know.This seems really weird to me, this is my first foreign car. I am used to chevys and fords. Can someone please help me. This is so annoying and embarrassing.

Should help you in diagnosing it.

Already did that, I got a neutral safety switch code.

Hi,

There are mutliple possibilites, but timing is not one of them.

1/ spark plug cables and ignition cables can be old and invisibly cracked, thus leading the spark away when cold.

Normally you should be able to hold the cable in your hand whern the engine is running without feeling anything (try this with cold engine)

2/ spark plugs worn out

3/ cold start sensor out of order or : like I had : oxidated connection plug on the sensor

4/ injection computer blown. with these engines letting the starter run without the sparkplug cables in their place (often done for measuring compreesion or after replacing timing belt) or running with bad cables causes reflux of the jolt into the comuter and thus blowing it.

5/ oxidation pon other contacts.

Try the simple things first!

Thanks Steven, I really apprecate the help. I just changed the spark plugs, but still doing the same thing. I am going to change the wires and check the cold start sensor, like you said.

ignition wires increase their resistance when temperature increases....so its a big possibility..

I replaced the ignition cables and the cap of the delco (? right word?) and my starting problems are over.


If your car continues to start badly : there is not only a cold start injector, but a cold start sensor (these MA70 are really full of sensors
