See there were several postings. Was internal fuel tank screen good when pump was changed? Was disposable fuel filter changed? I had similar problems and it turned out that the internal filter screen broke apart and clogged the fuel lines.

The crankshaft sensor was also bad as fuel pump was tested during internal tank filter work.

Also check your injector wires. Even having fuel pressure is nothing if the injectors are not opening to let fuel into the cylinders.

1989 300 SE mercedes benz dies after driving for 5 to 10 miles and will restart after it cools down. start easy and idles ok.

Could be the egr valve is sticking open. I would try diabling the valve by pulling the vacuum line off the egr valve vacuum port. You can plug the hose with a golf tee or bolt to run the test. Then drive the car on the highway where it would normally act up. If it still acts up, put the vacuum line back on the valve and check for other leaks, such as vacuum leaks--maybe the intake manifold gaskets.

Does a 1993 k1500 have a fuse for the injectors?

when engine stalls if you try to restart it check the tachometer. If the tach isn't moving then you proboubly have a bad crank senser which is killing the power to your fuel pump and your coil making you lose fuel and fire.

1996 intrepid was hard to start over the last week or two like it needed fuel . then today it just stopped turns over and tried a different crankshaft censer any help will be appreciated

More info would be helpful. Any codes popping up? Start from there and if codes, then that will point the direction you need to take. I have a 1996 Intrepid 3.5 and a quick guess is that you have a fuel delivery problem. Either faulty fuel pump, fuel pressure regulator or fuel line issues. Sounds like maybe an EGR valve problem too? All cars with over 100K miles have carbon and sludge in the EGR system which includes the pipe, passage from the egr valve to the intake and intake manifold. You might have a simple carbon issue. So, remove the IAC and clean the **** out of it with carb cleaner. You will be surprised how dirty it is. This is a 15 minute job. The IAC controls airflow and if the pintle is not moving per the ECM due to carbon, then it will start and run rough. Could be that your IAC needs to be replaced. Need more info here from you.
