So you have a crank no start?If so have you checked for spark and actual fuel pressure? Also have you checked the coolant temp sensor?

Yes a bad coolant temp sensor will cause it to not start and a whole lot of other symptoms. Also it has spark correct?Also inspect the inside of coolant temp sensor connector see if the terminals are blue or green instead of silver if they are you will need to replace the connector.

Yes, the pins are silver. The wires going to the sensor are black and yellow. When I crank it over, it really wants to start. Then I can smell lots of unburned gs fumes. Im gonna purchase a new sensor tomorrow.I will let you know the outcome. Thanks muchly!

I also measured the voltage coming out of harness, into the sensor. It measures 5 volts. And im sorry, the connector is white. Looks like its been replaced before. Can see where wires were cut and spliced w/connectors.

Thats normal for the 5v sounds like the sensor is bad and the car is flooding. Try holding the gas pedal all the way to the floor while starting it see if it starts.

Thats when it almost starts is when I hold it to the floor. And youre right, it floods out.I hope thats the problem. I just replaced the pcm today with no change. Ive dumped 600 dollars into this thing, just throwing parts at it. If this dosent work, then I dont know what to do.

You should have talked to me before changing the pcm I have replaced very few of them on those cars. It really sounds like a bad coolant temp sensor most common cause with those symptoms.

I replaced the oolant sensor, no change.A couple months ago, everytime it got to about six grand while driving, it was like no exelaration after that. Seemed like it was stRving for fuel. I drove it for awhile and then I couldnt a excellerate past about three grand, with the same probm. At that point, it would still start, but everytime I revved it past a ouple grand, it would just cut out again.I pulled the injectors a d cleaned them. When I put them back in, thats when this no start thing started.I got some used ones a d put them in. It still wouldnt start. Do you just think that its the injectors?And thats where it all began?I dont have money for new ones.
