#1 NEED TO VERIFY SPARK AT SPARK PLUGS # 2 CK FUEL PRESSURE AT SCHRADER VALVE ON FUEL RAIL ,,PRESSURE DEPENDS ON TYPE ENGINE ....IF NO SPARK AT SPARK PLUGS CHECK SPARK FROM COIL WIRE , IF NO SPARK AT COIL ,CHECK VOLTAGE TO IGNITION COIL SHOULD BE 12 VOLTS, IF NO VOLTAGE AT COIL ( KEY ON ) CHECK FUSES THEN IGHITION SWITCH. IF NO FUEL PRESSURE AND FUEL PUMP RUNS REPLACE PUMP .. CK VOLTAGE TO FUEL PUMP WHILE CRANKING . CK USING PUMP GROUND WIRE AT THE PUMP CONNECTOR THIS WILL PROVE GROUND ALSO. USE TEST LIGHT TO VERIFY
Do you have a Bypass Ignition System or a Non Bypass Ignition System?
I have a 1989 astro van i cant get power to the fuel pump and injectors i tested the wireing that powers the ecu computer and its getting power but noting from the ecu out to pump or injectors please help if any one could

What you have to do is check and see if you have fuel pressure.You have to remove the engine cover to check it.If you don`t have a pressure tester then remove the air cleaner hose to the engine and spray it with carb.cleaner or brake cleaner.If it starts for a few seconds then it is more than likely a fuel pump.If it does not start then you have to check for spark at the spark plugs.Make sure you check more than one plug.If no spark then you have to check the distributor cap and rotor.Make sure the rotor is good and cap also.Things that can cause no spark are the ignition module,coil,and cap and rotor.Hope this helps.Good luck.

I have a 1986 Chevry Astro Van that I learned abot the hard way that was doing what yours is doing. In my case, after being ripped off by one fast buck mechanic after another, i learned it is the oil pump computer that probably needs to be replaced. If it does not read the right oil pressure, it won't start. But, what myinsance mechanic did was to run a wire from the ignition to the starter, etc. Cost was $11.--/ after he first pt in a starter, fuel pump, new main engine compter, etc, none of this helped it start. Then he did the hot wire thing, bypassing the oil pump computer. I undersatnd that compter is about $65.00. I got ripped off to the tune of 1,000.00 befoer thru trial and error the real cause was discovered.

Check to see if the fuel pump is kicking in,
when you turn the key on without starting the van you should hear it kick on for about 2 seconds,
It could be...
A clogged fuel filter...
Blown fuse for the pump..or bad pump relay..
No gas
Bad fuel pump
