Most temperature sensor decrease in resistance as temperature goes up. As resistance decrease, current increases while the voltage remain constant, which is usually 5 volts. What you can do is unplug the temperature sensor, that should keep the car from dying for diagnostic purpose only.Look for a plug that is similar to the temperature sensor. Sometimes, a wire terminals is not plugged in where they should be. You know the the temperature sensor is working because the computer responded by turning the engine off. Only that it is connected to the wrong input of the computer thats why it does that. To sum it up look for similar looking wires terminals they maybe crossed. Look for sign where a wiring had been repaired. they may have been connected to the wrong place. Hope this helps.

What causes no injector pulse on one bank when engine warmes up

it could be a bad connection or wire for that bank and when the circuit gets warm it causes a connection problem or it could be a bad driver circuit in the computer.

Can a dirty injector cause a cold engine to be a hard starter ?

yes it can, i had a corvette with the # 6 fuel injector that was bad, it would start up, and run a few seconds , then die, wait a few minutes, crank it again, then sometimes , it wouldn't start, then i would wait a while and try it again, and it would fire up, and run a small amout of time , and then die, i checked the fuel injectors to see which one was not working, and found out that it was the # 6 injector.

My 91 chevy corvett fuel pump want come on untill the oil pressure turns it on.I checked the fuel pump relay and it checks ok Ireplaced it anyway. i just finished replacing all of the fuel injectors in it...

I hope this diagram is correct? At the relay, the relay has two sides, the load side carries voltage to the pump, that is the line that looks like it switches between D and E. The control side of relay is on the right, that side needs voltage and ground. The voltage comes from ecm, usually a green wire with white tracer. Did you check for voltage on that wire, engine cranking? Even though the fuel pump gets voltage through the oil pressure switch, does the vehicle start and run? If more than one problem, I'd have to check rpm signal and where applicable, security system.
I was just curious, engine cranking, you have spark at the plugs and fuel injector pulse?

First starting in the morning the 1996 jeep cherokee classic fires right up, backs out of the driveway, is able to go into forward and go down the block, at the stop sign there, it dies, and, until it...

Check out your cold start choke. It is designed to cause your fuel mixture to run "rich" until it warms up. It is basically a heat sensitive coil that reacts to heat from the exhaust manifold.

91 mighty max wont start when cold

Next time when cold and it will not start remove a spark plug or two and see if the engines flooded. If so there are two things that come to mind; 1, worn injectors, leaking as engine sits with time causing difficult starts 2: bad oxygen sensor, if failed engines tend to run rich and the ECU may have your injectors pump heavy amounts of fuel to keep from running lean; often times you'll see poor fuel MPG if O2 sensor failed.

I hope this may have assisted you,

85 vette fuel injection fine after first cold start then runsroug

something wrong with mixture thats for sure,but only being a europeon mechanic without a lot of experiance on yank tanks iam not sure exactly what the problem could be ,but if one bank of injectors are not operating ??have you checked for a feed to the suspect bank ??(electrical)because in my eye if they operate when cold then stop when autochoke shuts off then its a fault with the ECU or a sensor on that bank??

idle air control is used for assisting in fold starts. It sounds like its not functioning propperly. FYI your car is not carberated, its called a throttle body.

91 jimmy starts cold, runs rough hot, dies when put in drive

Try to unplug the mass airflow sensor and start it. It will idle higher but should run fine. If it works then you need a MAF sensor. Be sure you have an OBDII code puller to clear the computer when done
