Crank but no start, no spark, no oil pressure at key on
Alright you scallywags, you see the title. Van
cut off on me in a parkin lot. Crank but no
start, no spark no oil pressure at key on. Fuel
pump is priming, in fact we just replaced the
ICM, and now the fuel injectors are spraying
and they weren't before. I replaced the
ignition coil. I've since learned from my
mistakes buying new parts for diagnosing,
and bought a multimeter and a test light. I'm
getting power to my ICM, going to check for
ground. I saw on a Chrysler forum someone
had the same problem and It was the
camshaft sensor. I have a manual but it's for
trucks. It says they didn't put on crankshaft
or camshaft until 96. There's two sensors on
the passenger side that have one wire. I cant
seem to figure this one out boys. Anybody
got a clue?
Ignition module in the distributor ? Why chrysler advice for a gmc ?? It could be a crank sensor if you replace the ignition module and still doesn't fire up , couldn't tell you how to test either of those
Remove the distributor cap and crank the engine. The distributor drives the oil pump. If the distributor rotor is not turning while you're cranking the engine the timing chain is broken. This will be the cause for the no spark and no oil pressure. To get further verification of a broken timing chain do a compression test. If all cylinders test very low or zero and the distributor rotor is not turning the timing chain is broken. It could be a broken camshaft, but that's highly unlikely. Hope that helps! Jim
Check engine light shining bright. No codes. No oil pressure. No spark. Distributor is turning. New ignition coil, new Ignition control module. Beatupchevy I dont have a crankshaft sensor. I'm going to upload some photos and hope there's something I'm looking over here. Thanks for all y'all's help. I checked for the distributor Js, and she's spinnin like a top. The battery was a little low after I replaced the ignition control module, so I'm gonna charge, and back at it, after some much needed physical and psychological rest.
That's good news, at least we know the timing chain is not broken. Since this is a 1995 model it may be OBD I. To get any trouble codes out of the computer, if it's OBD I you need to jump terminals A and B on the diagnostic plug (ALDL connector) under the dash. Then turn the ignition on to the run position. The check engine light will begin flashing out any codes beginning with reference code 12. You'll need to count the flashes. Code 12, for example, will be flash, pause, flash, flash. It will flash the code 12 three times. Then a longer pause and the check engine light will start flashing out the actual trouble codes. Each code will be two digits and flash three times before moving on to the next stored code. Once all the codes have been flashed out reference code 12 will begin flashing again. If you disconnected the battery the codes will be lost on the OBD I system. If you can't flash the codes it's the OBD II system and a code reader can give you the trouble codes. Those codes will be four digits and begin with the letter "P". Hope that helps! Jim
On the OBD I connector terminals A and B are the top two holes on the right of the connector. Jim
I've ran the codes, but the only time I got any was when I accidentally ran them with the fuel pump relay out. It gave me codes 34, 43, and 54. Thought of it as a false flag, but I did check the map sensor, it's good, I haven't checked the knock sensor, and I half ass checked the fuel pump relay. I'm goin to get a couple pics presently
I'm not sure what this sensor is....passenger side In between the spark plugs ish, one wire
The day she cut off I found this spring on top of the intake manifold, sorry for blastin the thread. just a few more break downs and I might understand how an engine works HEH.
Alright well I decided to take the ignition coil off to clean the connections just in case, and I noticed it was blown...the first thing I replaced...when I got a new one she.fired.right.up. thanks for all your help guys, honestly just being able to talk to some knowledgeable people helped me not feel so hopeless, which is what I needed. Peace
