Cranks but no Start

[alorenz]

On my '91 I had a coolant hose leaking and had to remove the intake manifold in order to replace it. I put everything back together today and now the car cranks but will not start. I verified that all electrical connectors are hooked up again. Prior to this work the car was running perfectly fine. I checked codes and the only one that came up was 67. Can anyone think of something I may have done wrong or missed when I was putting it back together that could cause this?

I would double check you don’t have pin loose or a pinched wire on the ignition control module

Maybe also missed reconnecting a ground strap

Checked again and everything on the DIS looks fine. Don't see any damaged or pinched wires. Verified again that all electrical connectors are plugged in. Still cranks and won't start. Kind of at a dead end here. Not sure what else to do other than maybe take off the intake manifold again to see if it could be something underneath.

Did you verify fuel pressure at the Schrader valve, it should shoot up when you depress it
plugs wires weren't removed correct?

Flat ground strap attached to the left rear of the engine?

Been there. If it ran before you worked on it.....Might be the way to go. Sometimes you have to redo to even see what might be missing. it happens

I 2nd this. Flat ground strap on the passenger rear of the engine compartment. It connects to the back of the intake manifold. Easy to miss during reassembly.

Don't forget about putting the bolts in the crossover tube.

Thanks to everyone for their suggestions. Turns out the battery I bought at Walmart about a year ago went bad already. Had enough power to crank but not enough to start.

That's simple enough.

Glad I found this post. Had some of the same problems with my car not wanting to start all of a sudden. Cranks but nothing. Originally when I bought it the DIS module was missing the ground bolt but I put that in and it fired right up. After driving it a couple times it died and wouldn’t stay running. Now it won’t start at all. Car through a code for a bad CCRM but I put a known working one on and still nothing. Wondering if my battery could be bad now

Have the battery load tested at an Auto store.

Can they check the battery without it connected to the car? And does the metal piece that holds the battery in place act as a ground at all? Or just strictly to keep the battery in place? I ask because mine is broken

They can check it out of the car. Hold down bracket has nothing to do with grounding.

I swapped it out with a good one. Still nothing, it just cranks faster now. Only codes are the one telling my the battery was unplugged and one telling me everything is fine.

Disconnecting the battery erases the stored codes.

A common problem is the crank position sensor failing because it got shorted out by a leaking water pump. I would have expected a code 14: PIP circuit failure if so, but the only one you reported was for the CCRM.

I would suggest checking for spark. Get one of these if you don't have one:

If you don't have spark, check out the DIS:

fwiw, on these cars any time I had a ccrm code it was never the ccrm that was bad. So, I would be looking at the dis or the crank sensor as more likely candidates.

 

[ErykJ]

It was the DIS, thank you

I dunno, I'm suspicious of that "water pump leaking kills the sensor". My first one died with a good WP. Second one had a leaking pump, but sensor was fine.
