timing marks off???????

Mike,

At the newest, yours is a 95 CMFI system with OBD 1.5 engine controls. 96 and newer use OBDII... whole new ballgame. The computer system is totally different along with a different injection system and more, (and different) sensors and actuators. Not to mention wire harnesses and PCM. I suppose it could be upgraded but, lotsa money and time to do it.

I apologize for not asking what year your vehicle is... The pictures above are for OBD 1.5 & OBDII, and depending on what system yours has, the distributor might or might not look like yours. 95 was a changeover year and could have any one of 3 different systems. Under the dash on the driver side is a connector, which one looks like yours:

Yep......Its OBDII and A 1995.

The lower connector in the picture is used on OBD1.5 and OBD2. If there is no crankshaft position sensor at the dampener, your engine is OBD 1.5 with CMFI. It is a step up from OBD1 and it will give four character DTC's that start with "P" rather than the 2 digit DTC's. OBD1.5 does not have all of the capabilities that OBD2 has, and it requires an enhanced code reader or scan tool to retrieve DTC's.

Moving right along here.... Does your distributor have 2 electrical connectors on the side and look like this:

The harmonic did slip. The new one lined up perfect with the notches on the timing cover. I'll try and start it tonight. I left the light on under the hood and the battery is stone dead. This has to be OBDII, its has a crank sensor and did disply PXXXX codes. The vin suggest its a CPI system. Can I upgrade this to MFI?????? The timing cover is plastic but the upper intake is large and metal.

Nevermind the picture in my previous post, your distributor does NOT look like that.

Large metal plenum is CMFI.... OBD 1.5, one injector, (batch fired), 6 poppets, nut kit, (fuel lines inside plenum). Requires different lower intake manifold, different plenum, different spider injector pack, different fuel lines to the injector pack, different fuel pump, (higher fuel pressure), different PCM, wire harness, different throttle body, different air intake set up. That's the obvious stuff, there's probably some stuff I can't remember, lotsa work, lotsa money but, it can be done!

Let us know how it starts and runs.

It started right up ran perfect...Thank god!!!!!!!!!! It does have single injector, 6 poppets, and nut kit. I'll leave it be for now.........

Good! Thanks for posting back with the progress, and the fix. I don't think I've ever seen a dampener slip on a 4.3L guess we have to put that one in the "memory file".
