My girlfriend was driving her car one day, I was in the passenger seat, when all of the sudden it just turned off. It would not start again. I thought I smelled gas for a minute or so. We pushed the car to the side of the road and it just wouldn't start. She had it towed home. She took it to the shop and they said there was something wrong with the PCM cause their computer could not get a reading, but other opinions suggest that they did not have the proper equiptment to daignose. She had someone else tell her the it could be the fuel pump. So it was towed again to go have the fuel pump replaced. It still didn't start. This is about 650 dollars later and we still don't know what's wrong. I am desparate to know what is wrong. The starter turns like normal but the engine just will not start. The fuel will not get to the motor, no pressure in the lines, the lines are clear. The fuses are good, the filter has been changed twice. What could be wrong?

I think if I had paid that kind of money to have the vehicle repaired, and it wouldn't run, I would be just a little p*ssed off! First of all you are being taken advantage of, and you need to ask them why they charged you to fix it and didn't fix it. I would demand my money back or something. Many things can be the culprit. The crash emergency shut off could be tripped and needs to be reset. It is either accesed in the trunk, or under the dash in the middle of the hump where the carpet meets the firewall. A blown fuse, a fuel pump relay, a bad pressure regulator, or in a long shot; the new pump is no good. It is a possiblilty the computer is bad or not getting the proper ground or power. The first thing to do is; Have someone (who knows what they are doing) pull the codes from the computer with a scan tool. If there are no codes there, then you start looking for a mechanical reason, or an electrical problem. Clean both battery terminals, and any ground straps that attach to the body to insure the computer is getting the proper power and ground. Get a can of Carburetor/choke cleaner, and remove the snorkel from the throttle body. Have someone else work the inside stuff. Hold the gas pedel on the floor while you spray about 2-3 seconds of this into the intake/throttle body. Get the spray out of the way, and have them try to start the engine. If it starts, and stops again, you know its a fuel problem. DO NOT spray while they are trying to start the engine unless you have a wish to get burned. The fuel system will have to be repaired. Check that switch I mentioned before. When you first turn the switch on, have the gas cap off, and listen inside the tank for the pump to come on, to make sure the new pump is coming on. It should run for a few seconds and stop. The pressure regulator can be bad, as this will also cause no fuel pressure. If its the ECM you will not hear the injectors fire, but you should use a noid light to check to see if you are getting the signal from the ECM to fire the injectors. You can use a hose, and place it by one of the injectors, and the other end listen to. You should hear the injector clicking when you are trying to start it. If they don't click, then you may need a new ECM. Remember; once you remove the battery cables, you will loose the information (codes) stored in the computer, so its important you have someone get those codes in order to tell much about it. Honestly; you should have a real mechanic take a look at it, and tell you what the problem is. If he knows what he is doing, he should be able to tell you what is wrong within about an hour at the most.
I hope this helps you out. Good Luck!!!

If you can hear the fuel pump hum when the ignition is turned to the on position its a slam clogged up fuel filter. If not from what you described it's the computer. You can go to a junk yard and purchase one for a fraction of the price of a new one and swap it out. This would be much cheaper than getting it towed somewhere or taking it to a shop, paying for a diagnostic fee and getting a new computer.
Take the trip to the junk yard. I'd get 2 of them just in case. and it would still be cheaper to buy them and try them than going to a shop And paying for a tow bill again

How have you determined there is no fuel in the lines? There should be a schrader type valve along the fuel rail that you can depress briefly to see if you have fuel pressure. If OK then you need to have a competent mechanic hook up his computer scanner to the OBDII outlet to read what the computer is telling the scanner. If the PCM is a problem it may have to be replaced, but get some more information before you make any costly decisions.

If each and all of the coolant leaked out of the heater middle you're able to have one vast mess on your floor. You scent antifreeze with the aid of fact the scent is coming in via the heater vents. i will wager you have a bad hose someplace decrease than the hood.

If they couldn't get a reading on the PCM it's probably grounding out.
Therefore the 1st shop was probably correct.
