Sounds like you have covered almost everything!!! It could be the control module or the fuel pump relay.

1998 Dodge Stratus 2.4l bogs down suddenly while at cruising speed


You need to get the engine trouble codes by performing the "keydance" or using a code reader, then start checking fuel pressure at pump and regulator. Best luck. Amclaussen.

My 1993 nissan sentra 1.6 wont run and check engine light wont turn on,bulb is ok


Could be any of several things. If the crank sensor is marginal and not sending pulses, the fuel pump is shut off. This is for safety. The pump is energized for a few seconds as key is turned in preparation for starting then engine must rotate normally to keep the pump on. If it stops, in a few seconds the fuel is cut off.

My van sedona 2005 after i stop it,it won't restart unless i press a few time on the gas pedal ,and also runs rough a bit what could be the cause of it.


May be the starter or fuel pump. Might not be getting gas after turning it off. the gas may be settling to fast into the fuel pump and none staying in the engine. My friends SUV does not start unless you pump the gas pedal. Not an expert but its what i know it could possibly be.

The engine on my 2000 MPV cuts out and dies when I press the accelerator. After it sits for an hour or so, I can travel for 20 min. or so before the problem starts again. HELP!


if its been a while change the fuel filter and then have the fuel pressure and volume checked.these symptoms are very common for a fuel pump problem.

Engine quit when stopped at stop light. Acted as if it was choking then died. Tried restarting. Turns over strong, no start. Thought maybe no gas. Added gas after about 30 minutes. Started first try....


Sounds like the fuel pump is going out. Replace the filter first, as it's only $10. If that doesn't fix it, then it's probably the pump, which is $250.

Engine will turn over, but will not start


Suggestion, don;t try and start the car with the gas pedal pushed to the floor. Asking for trouble in the future.

Could be a fuel pump, clogged fuel filter.

Check engine light on? If so, Have the code read/scanned at your mechanic, or your local auto parts superstore.

1999 toyota tacoma Sr5 won't start


Check for fuel pressure when starting. Fuel pumps have a check valve in them that keep fuel in the rail at the injectors. If the check valve fails, the pump has to pump fuel all of the way up to the engine. Same thing with hot no-restarts. Fuel pump.
