2002 express 1500 van, 37,000 miles,put 93 octane fuel in tank, drove 50 miles okay, then a week later started running rough. last week, started van, let it warm up,idled fine for 30 minutes, put in reverse, died. restarted, ran rough under load, drove 8 miles to gas station, put in heet and topped off tank, would not start, left van at station, came back next day, started rough, ran okay for 5 miles, then started running rough again, died 1 mile from house, restarted, got to drive and died, will not start at all now, Have changed fuel filter, now thinking about fuel pump, can i test it before trying to remove it to see if it is putting out the correct pressure. Trickle charged battery back to 13 volts. Engine turns over, will almost start the nothing

Also, when you have the dog house off, remove the distributor cap and check for moisture.
It’s dry like the dessert

Remove dog house locate test port and install guage should be 45-60 psi

Is Check Engine or Service Engine Soon light on?
This van for some reason has no engine check light. Maybe bulb is burnt out. When I turn ignition on it should show the engine light. But I have a scanner and check it all the time.
Do you think maybe a non working light would cause this?
Do you think maybe a non working light would cause this? No ,just burnt out bulb probably ,how long have you had this van ? That's right ,turn the key on an check engine light should come on , won't go off till vehicle is started an running. What engine does your vehicle have . Same vehicle as above ? 2002 express 1500 van Does it crank , turn the key an starter engages an spins the engine around .
What all have you done to your vehicle ,beside checking fuel pressure ? Has spark ? good compression ? No codes but scan tool does communicate with PCM/ECM just no codes ? Do you hear the fuel pump running ?
Do you know how to test fuel electrical circuits ? Watch the videohttps://www.youtube.com/watch?v=McnXLcJN...
