The problem is almost certasinly that dried gas residue has plugged the injector spray tip, most likely they are ruined and will need to be replaced, the only way to determine this 100% is to have a dealer run a injector flow test, they may be able to power clean them, here is the price of the replacements.

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.

2000 chevy s10 starts fine but dies out when push


Have you changed the fuel filter lately? If not do so. Sounds like fuel restriction. Filter usually on frame rail passenger side. Good luck!

91 RS dying


First off, I think you bought a raft of stuff you didn't need on that repair job! The sound of it at this time is that probably the fuel pump is about gone.You need to measure the fuel pressure (engine running) at the fuel rail (the test port looks like a tire valve) above the injectors. The pressure should be in the 45 to 55 PSI range. If the pump is toast, it will be much lower. The pump resides in the fuel tank. You probably have the check engine light on. If the code(s) are read out with a scanner, it will likely point to the fuel pump.

Will not idle


fuel pump is in the tank. first get a spark tester and see if there is spark.if there is ,get fuel spray into the throttle body and see if it starts then dies.that would mean a fuel problem.sometimes banging on the tank gets the pump working again.take the cap off and have a look inside.

Alt seems ok but strong fuel smell and new plugs black


use a scanner sound like a bad sensor .mass air flow - map sensor - coolant sensor. check vacuum line to fuel pressure regulator if wet with gas replace fuel pressure regulator. make sure yours spark pluge the right heat range. also change air filter. check charcoal canister. check oxygen sensor and egr valve. make sure its not stuck open.

1995 AUDI 90 CS - Hard to start... spark & fuel OK


Have you tried replacing the starter? I know starters can go bad if the car is not started or run for a long time.

I am getting the same car, with the same issue.. it sat for 2 yrs and won't start.

My mechanic told me it is probably a starter.
