Was running low on gas. The next day - hard start up. I initially thought it was a fuel related blockage. The car loped and turned off. I added gas. No improvement. I have replaced fuel pump, fuel filter, fuel pressure regulator, fuel injectors, ignition coil, spark plugs, and throttle position sensor. No improvement. What else can I do? Where can I find a picture of vacuum hose setup? The diagram is not much help.

I did the spark test. I pulled a spark plug and had someone turn ignition. The plug sparked on and off repeatedly. Can the return line be blocked? How do I check that. Do I have to drop the tank and disconnect the line at the fuel pump? Also, I have replaced these parts over time. I switched the position of the electric relays the control box. No change. Any insight of the electronic control module. The computer brain?

wow you replaced alot of parts already did the check engine light come up? if it did you can get the code and go from there. if not the the first thing you have to do is find out why it wont start does it get fuel or is it no spark, you can check that by disconnect the return fuel line first and turn the key to the on position and have some one look at the return line if the fuel come on that means your fuel system is doing good then go to the electrical system. take one spark plug out and connect it to the spark plug wire and crack the engine over and have some one look at the plug if the plug does not spark then you have a electrical problem. but also it could be your ignition swich is bad or ignition control modular. well good luck keep in touch if you have more questions

did you bleed the lines, when you installed the fuel pump and gas filter, from air in the lines.how good is the spark, is it blue spark?, if its a yellow spark, then its a weak spark, check the module, take it off and have auto zone to check it.what about the fues that runs the pump, is it good? this is just a few things you can check out. good luck with your vehicle.

did you pour gas directly into the injector to see if it would run. it could be a relay or a fuse. you have to make sure that the gas is flowing to the injectors. also you can go to an autozone and they have the books underneath the counters. or you can ask one of the part sales attendents to pull up a diagram of your valcum hose system.

Check the tail pipe for blockage then the catalytic converter.
My guess.

Think about all the money you have spent swapping out parts. take it to a dealer and spend the $100.00 to have them tell you what is wrong.

I don't see fuel pump listed.
Have it tested for pressure and flow.

Sounds like you need to take it to a repair shop.

you have a electronic switch on your distributor could be bad.
