Have intermiate starting problem. Sometimes will start up and sometime cranks several attempts then will try and start then once finally starts after many attempts will chug for a few seconds then runs...


Sounds like you may have a fuel injector bleeding off when you shut it off, causing a flooding problem. If you can test the fuel pressure to see if it loses pressure after the engine is turned off that would help diagnose the problem. Depending on what vehicle it is, it could also be a bad fuel pressure regulator.

My van wont start no fuel or spark ?


Sounds like it could be the ignition module in the distributor. You have a throttle body instead of a carb. The injectors get a ground signal from the engine computer when they are supposed to open. The ignition module takes a signal from the pickup coil in the bottom of the distributor and decides when to fire the plugs and also the injectors.
If the injectors and the coil has power, it could be the module or the pickup coil.

1989 ford escort turns over but wont start


if all you did was this...and and put a new battery in and still wont start...if you have went thru your plugs..wires..distributor..ignition coil...made sure your getting spark..if not..check your relays and fuses..preferebly one that deals with spark and timing for injectors..if everything is fine to that point...then try a crankshaft position sensor...it tells the pcm timing for fuel injectors and fire to the ignition coil...hopefully this helps.

I have a 91 chevry lumina 3.1 v6 i put and new fuel pump and filter and relay and check the coils they are fine i can start it it will run for about 5 mins and stops then restart fine and dose it again...


You've done well by ruling out the most likely things first. You need to next check the condition of the "ignition module". When this module starts to heat up, if bad, it will cause the engine to shut down rather quickly.

Trouble starting after warm have to turn over forever


this could very possible be a bad coil , or a bad fuel injector, check the coil to see if you see any cracks in it , in which it would be jumping fire, or it could be a bad fuel injector, you can check each fuel injector, by taking a mechanics stethoscope, and putting the probe to each injector 1 at a time, and have someone crank the engine over to see if you hear a clicking sound coming from the injectors, the one that has the weakest sound or no sound is the bad one . also, you can disconnect each injector wiring connector, 1 at a time, and hook up a noid light to each injector wiring connection, and then turn on the ignition key, but do not start the vehichle, this will show you if there is current coming from the wiring connection to the injector, you can purchase the noid lights at a auto part store. hope that this information has been helpful to you.

What is ASD RELAY


The power supplied to the fuel pump, ignition coil, fuel injectors, and parts of the power module is controlled by the logic module through the Automatic Shutdown Relay (ASD); the idea is to shut off fuel pressure and the ignition systems when the key is turned off to prevent fires, dieseling, and other problems.



The ASD relay is closed (allowing power to flow through it) when the ignition is first turned on. If the signal from the ignition reference is lost while the engine is running, or if the turbo boost pressure reaches and exceeds the over boost cut-off point, the logic module cuts power to the ASD, which in turn removes power from the fuel pump, ignition coil, injectors and those parts of the power module. This causes the engine to shut down.


Failure of the automatic shutdown relay is often shown as inexplicable stalling or refusal to start.

1995 Ram 1500. Just died? No votage to coil, no spark?


The power supplied to the fuel pump, ignition coil, fuel injectors and parts of the power module is controlled by the logic module through the Automatic Shutdown Relay (ASD):
The ASD relay is closed (allowing power to flow through it) when the ignition is first turned on. If the signal from the ignition reference is lost while the engine is running, the logic module cuts power to the ASD, which in turn removes power from the fuel pump,ignition coil, injectors and those parts of the power module.  This causes the engine to shut down.

Failure of the automatic shutdown relay is often shown as inexplicable stalling or refusal to start. The ASD can be triggered by a broken wire or short in another place, e.g. the fuel pump.  Hope this helps, and did you try to retrieve any DTC codes?? Be glad to help friend.
