2.9 Won't start.

I will almost 99% gurantee its not the chain. In 20 years here i dont think ive ever heard of a 2.9 chain failure.

It could possibly be the distributor itself. IIRC code 18 usually relates to that. It may even be wiring or an ECM failure

Well I took timing cover off and just double checked chain and timing marks everything aligns on the cam and crank I am assuming y’all are thinking maybe distributor itself and wiring I’ll check all that over but how can I possibly test to see if ecm is bad I hear pump when I turn key check engine light comes on with key in on position then goes off like normal I have spark so I’m at a loss here I don't know a hole bunch on distributors and how they work or how to tell they go bad.

Also the Hall Effect sensor is that also known as ignition pickup coil? located on the distributor. im going to pull the harness tomorrow and check that and make sure all the wiring to that is good i have heard of the hall effect sensor going bad in the 2.9s but like i said ive never really got into a distributor before... thanks for all the help so far.

So I replaced distributor but I have no spark when spout is connected but when pulled it has spark but starter sounds kind of like it’s in a bind plug back in spins over great just no spark I haven’t replaced TFI yet don't know if that would cause my issue?
