Dead Jeep
I'll give you guys a shot at this.
My CJ is dead. It will turn over and not start. I was driving down a dirt
road, from the end of the trail to my truck and it back fired then quit.
Yesterday, I checked it and it is getting spark, fuel and the timing seems
to be okay (TDC, #1 piston is up and dist. is on 1).
It is a 360 with a Pro-Jection and GM HEI, 727 trans, D300. It's first run
was Saturday, prior to putting the 360 in I put a double roller chain and
gear in it. When it died I looked down at the gauges and the oil pressure
was normal and the temperature was normal.
I am baffled. I put a new module in the distributor, just in case.
Everything else in the distributor is new.
TIA

Re: Dead Jeep
Hi James,
A back fire is always ignition, but eliminate your injection by
spraying a couple of ounces of gasoline onto the throttle butterfly, and
firing. No fire, a commonly overlooked failure is a leak in the rotor,
where it looks like you have spark, but none reaches the plug. Fire,
look at your crankshaft position sensor, on your balancer.

Re: Dead Jeep
I tried starting fluid with no luck. Every once in a while it will "pre"
fire and cause some flames in the TB.
There is no crank postion sensor. The FI works off the tach lead on the HEI.
I did replace the module in the HEI yesterday, no change. There is spark at
the plugs.
It really sounds like it jumped time. Does anyone know if there is a way on
the 360 that maybe, the gear on the cam that drives the distributor can
rotate independently of the cam? I am thinking some how the distributor some
how slipped 180*. I can't remember how the timing gear went onto the cam and
how they are related to the distributor drive gear.
Grabbing at straws right now, I thought I was a good "mechanic". This is too
crazy. I am willing to try anything. I have a friend coming over with a
compression testing gauge, although the compression seemed good on the #1
cylinder using the finger test.
Thanks,
--James

Re: Dead Jeep
It's not difficult to check for spark, just pull a plug wire and peel the
boot back to expose the contact. Hold it 1/4 inch from known good ground
and crank the engine over.
If no spark is seen, go to step 1 below,
1. Look closely at the two small wires on the pickup coil in your hei dist.
In fact, grab them and give a tug. These will often break from the constant
flexing they do with the movement of the vacuum advance. Often times the
insulation is not even broken, just the wire inside, that's why you want to
give them a tug.
If you did see a spark then a timing light will flash at cranking speed.
2.Hook one up and take a look at your timing marks with the timing light.
If your chain has slipped your timing will be way off. Having the rotor
point to #1 is only an aproximation. The ignition does not necessarily fire
when the rotor is centered on the contac in the cap. it's firing is
determined by the pick-up. You can be pointing to #1 with the rotor and be
a long ways off with the timing, enough to indicate the chain has jumped.
