Timing Chain??

Hi guys...newbie here

I've had my '94 GC Ltd for approximately 6 years and have had an excellent run with it. Very minor issues till now...

My engine (5.2 liter) died on me in traffic recently and though it cranks, it won't start. I had to replace the in-tank fuel pump a few years ago but this doesn't seem to be the problem this time (I put a little fuel directly into the throttle body but still no go). I have spark also so I'm leaning towards the timing chain being the problem...(214K on original 318).

So my questions begin

The engine isn't an interference type is it? (I don't believe it to be)

How can I confirm (prior to tear-down) that the timing chain is the culprit as I suspect?

Anything else I should be looking into that I may have/probably overlooked?

All opinions/assistance is appreciated...thanks in advance.
Jeff

It's not likey to be the timing chain.
If the chain (or sprockets) was bad, you'd hear it.
This isn't some rice burner with a rubber timing BELT. The chains in these engines generally outlast anything else in the engine. And they don't just skip a tooth like a belt can.
I'd be looking at electronic sensors first, starting with the crank posistion sensor.

Thanks for the info...I'l give that a check tomorrow.
A possible sensor replacement sounds a lot better than a timing chain job


Any other ideas if this doesn't pan out?

The CPS would be a great start like Kruz stated. Where in Hoosierland ?

Ok, I give up ....any tips on getting to the CPS? Let alone testing/replacing it...

Hopefully, I'm overlooking the obvious but I can't see getting to it with the engine in the vehicle
