IRONDOG442 Posted April 27, 2006 Report Share Posted April 27, 2006 Here's a problem I had last night and solved (after about 2 hours) lets sere how good you all are. I just did a head gasket job on a 1995 Cutlass Supreme 3100 SFI after I reassembled it, it would not start: Knowns: I had good blue spark at all 6 cylinders I had fuel being delivered Car had excellent compression (so the push rods were properly installed) All pigtails and vacuum lines were properly installed All ignition wires were properly installed Car was cranking and seemingly wanting to start but would not 1st question what would you do to diagnose this problem? After diagnosing problem how do you solve it? Quote Link to comment Share on other sites More sharing options...

fastbird232 Posted April 27, 2006 Report Share Posted April 27, 2006 What does the engine sound like when you crank it? Quote Link to comment Share on other sites More sharing options...

DiscoStudd Posted April 27, 2006 Report Share Posted April 27, 2006 Pull the oil fill cap and observe the rocker arms while someone cranks the motor over. If they aren't moving, then your timing chain is broken... Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted April 27, 2006 Report Share Posted April 27, 2006 oooh, that would suck, but definitely could be a possibility Quote Link to comment Share on other sites More sharing options...
mihela816 Posted April 28, 2006 Report Share Posted April 28, 2006 That would make a lot of noise though. Quote Link to comment Share on other sites More sharing options...
Bossman429 Posted April 28, 2006 Report Share Posted April 28, 2006 How long did you crank on it? Sometimes when we do HGs on 3X00s they have to crank for sometimes 10 seconds or more before they start. Just getting all the junk out of the system I guess, but I've seen it multiple times.

Intlcutlass Posted April 28, 2006 Report Share Posted April 28, 2006 a problem I had last night and solved (after about 2 hours) Can you replace a busted timing chain in 2 hrs? I don't think I could... so I was going for something more simple, yet diagnosis time still included. All it said was that all the sensors were plugged in, it didn't say they were all good...Thast why I thought crank sensor.... I donno.. I give... What was it?

IRONDOG442 Posted April 28, 2006 Author Report Share Posted April 28, 2006 Crank sensor was very close Turns out it was a blown fuel injector fuse: Why it was blown?? Crank sensor wire was pinched under the AC compressor bracket shorting it out and obviously not atomizing the fuel. Good guess !! Car Runs like a top now!! Just got to bleed the coolant system and fix the water pump steel line comming out of it ! Then the car is going up for sale. Quote Link to comment Share on other sites More sharing options...

It just sounded like it wanted to kill you.... Very simple solution however, but it didn't take me 2 hrs. to fix mine... Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted April 28, 2006 Report Share Posted April 28, 2006 That would make a lot of noise though. surprisingly, mine didn't. it sounded a little different since the camshaft/valvetrain obviously wasn't moving but it wasn't noisy at all. bent 2 valves and didn't even here that! the engine simply died. man that sucked Quote Link to comment Share on other sites More sharing options...
brianhasadd Posted April 28, 2006 Report Share Posted April 28, 2006 I think it's because you have a flat tire....but that's just my guess Quote Link to comment Share on other sites More sharing options...
