Car jumps from silonoid run 5 to 8 seconds dies can repeat over and over new fuel pump new ignission pleas help

You may want to do a fuel pressure test to start. The pump could be defective. The fuel pressure should hold steadily and not decline with the pump off. If the fuel pressure falls, you either have a fuel leak, stuck injector, faulty fuel pressure regulator, or a bad fuel pump check valve. If the pressure holds at the correct spec, note the pressure as the engine runs and then dies. If the guage shows correct pressure, you can then move on ruling out the fuel system.

the engine dies or the fuel gauge dies? has anyone replaced the fuel pump? maybe check the ground wire , its attached to the frame near the fuel filler inlet. (left rear wheel area)

If you spray starting fluid in the air intake, does it stay running? I would go to harber freight and get a cheap fuel pressure tester and hook it into the fuel line. It hsould be about 40 psi, and hold for about 30 minutes after shut down without bleeding down too much, like 5 psi.

Try this too. Turn key to ON, wait 5 seconds for the pump to shut off. Then turn key off and listen for the realy to "Cclick" under the dash (about 10 seconds). Repeat this. Then start engine. This primes the lines & injectors if you are getting bleed down due to a bad check valve in the fuel pump.
report resuts. pleasre rate assistance.

Fuel Pump relays are designed to run only momentarily until engine is running.Even if fuel pump runs it probably won't maintain enough pressure if you had no fuel pressure at the fuel rail.Sounds like a new pump is the ticket.

It sound like a bad alternator. it wont hold a charge

your igision mogulater is toast..that is what give power to your spark plugs.. check that

Float could be stuck, if it's carbureted or gasket under carb could be loose. Tighten and also put new filter in it. Could be bad injectors, if it's EFI which I doubt knowing the year. Could be choke setting wrong. I like manual choke myself. Try starting it with something holding choke open like a screwdriver handle. Something not too flammable.

Sounds like a large vacuum leak,low fuel pressure,fuel pressure regulator failure, idle air control valve stuck open,plugged fuel filter.Also check for good consistent blue spark at spark plugs or jumped timing chain.Hope this helps!

Let me explain real quick the fuel pump circuit, when you crank to start that is a straight circuit to the pump via a fuse in most cases, when the engine starts and you release the key the fuel pump relay is energized and keeps the fuel pump running, it sounds like the fuel pump run relay may be the problem with your car, replace it or bypass it to test, if you don't understand how a bosch relay is wired don't jump it yourself, you can burn up the wiring.

i gaurantee that it is the fuel pump ressistor up on the passenger side front behind head lamp assembly you will find the connector with two wires going to it. no need to remove old one install new one and connect wires to new one leave old in. dealer only part but not expensive. dont belive dealer when they try to talk you out of it. This is a kit to relocate a ressistor that has been installed in a poor location. I promise this will fix it. My wifes car did the same thing, took 20 minutes to fix and that is only because i am an electrician and am finicky about where to locate wires etc. the kit comes with installation instructions however they are a little vague. trust me. easy fix. my dealer tried to get me to leave car for repair and said it sounds like the theft detterent system. they were wrong and i was right. dont trust em
