Hey Jeff. Would you say the weather is pretty hot there? When the car cranks do you notice the GREEN key light flashing at all?
Yes its hot I havent noticed the green light flashing
Ok im gonna list 2 possible and common problems.
First could be a bad battery. The reason why is the engine needs only 10 volts to crank. But the immobilizer (green light) that system needs 12 volts. So if there is enough juice to crank the motor but not enough to run the immobilizer the car wont start. You could try jumping the car next time and if it starts thats your problem.
the second. With the heat the main fuel relays are known to act up. from heating and cooling the solder joints on the circuit boards crack. And with the hot weather and the even hotter temp in the car makes it expand and thre is no contact. Thus no fuel from the pump
SO you could have a weak battery or a faulty main fuel relay.
it sounds like the second one it really sounds like a vapor lock.so should i replace this relay
You can start with that. There not to expensive and fairly easy to replace.
Its under the dash to the left of the steering column. Way up above the fuse box. I would get the new one than crawlu under there and see if you can match it with whats under the dash.
stupid question were would that relay be located
one step ahead of ya. lol
Thanks alot i will give it a try Better to start with inexpensive stuff .You think thats mostly the problem
