Your pickup is on the bottom of your distributer under the cap. It looks kind of like a star. You will have to remove you cap, rotor and module to replace it.

Fuel starvation engine won,t pick up can only start by spray in air intake


Sounds like the fuel pump is defective, it is located inside the fuel tank, check for power at the connector when the engine is cranking over.

My car won't start I have changed the coil fuel pump fuel pump relay and the Mfi relay I now think its the crank shaft relay but I do not know help me !


Sounds like maybe the main computer is bad. When you cranked the engine there is not any indication that it is firing. If you have changed the fuel pump and coil and it still wont even fire, the computer is most likely the cause. Even if the timming was off you would still get some indication that it was trying to start although it probably would not if the timming was off, but the fact it's not even trying to fire yeah that's my take.

1999 volkswagon jetta v6 cranks but wont start


I'm having a similar issue with my '97 Golf K2 with a 2.0 I checked the resistance to the crank sensor and it was almost 900ohms with the replacement one being 500 ohms. Changed it, didn't work.


Mine was running fine driving 70MPH on the highway and just shut off. Now it cranks, fuel pump runs and it seems to be getting fuel but still no spark. I have a coil/module on order and will try it tomorrow.


UPDATE

Replaced the coil. Coil sparks once when you first turn the key on, that's it. crank sensor has already been replaced yesterday.
Injectors seem to fire (I smell fuel if I crank it a while) but still no spark.
I have 12V to the coil and 12V when cranking.

I see tons of posts with this issue but no resolutions. Come on somebody has to have been here before....

UPDATE #2

I do NOT have an injector pulse or a pulsed signal to the coil. When I crank the car the oil pressure light blinks on and off (just noticed this not sure if it is relevant)

I do get a check engine light when I turn the key on and when cranking, thought this meant ECU was good?

Any other way to test the ECU?

Could the pick up in the distributor be bad? Doesn't the pick up signal the ECU to fire the coil and injectors, I thought the crank sensor was just a TDC reference point?

1 ton Chevy G30 With 6.5 Diesel wont start parked uphill


If the pick-up filter is located at the front of the tank and the tank is almost empty the pump would starve for fuel.

Car stalled at30mph and wont start back up


  • Cranks but no start condition-do below to determine whether it's fuel or spark issue:
  • Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.
make sure it is getting enough gas pressure

Start with fuel system. Listen for fuel pump humm at fuel tank No humm check wiring to pump for power. Then check for spark at plugs and wires. Remove wire from coil and hold near engine and see arch when you crank. No arch. Replace ignition Modular inside distributor cap or cap or rotor

1997 dodge ram won't start. My fuel pump does not run and coil won't spark. Iv'e checked fuses and relays and they look fine. Could a bad fuel pump cause the asd to kill power to the coil?


First check any ignition/fuel related fuses. Check to make sure you have 12 volts coming into the pump and coil. If nothing to the fuel pump replace the fuel pump relay - if you do have power to the fuel pump then replace the pump. If nothing is coming to the coil it is either an ignition relay or a wiring issue. If you have 12 volts to the coil but no spark then replace the coil.
Also the fuel pump/relay would not kill the coil.

Dodge cummins won't start, fuel reaching injector pump but no fuel coming out of injector pump.


You said you have fuel flowing from the inlet line of the injection pump? But not at the injector lines?
