Okay beacuse of a registration issue, my car sat for 6 months while another car was used, it was working fine the whole time till then. Went to start it to get it ready for registration and no go!
Check fuel and spark, and found there was NO spark. Replaced Battery, Spark Plugs, Wires, Valve Cover Gaskets and Ignition Module.
Same thing NO SPARK ;-(
I got codes, and it showed two codes for the sensors attached to the air cleaner, which is accurate, since the air cleaner is off atm, and a crank sensor issue. So went out and replaced Crank/Cam Sensor (One Unit for that year). Still NO spark and, still throwing a crank sensor code, Sigh !@
All fuses were triple checked, and double checked for everything being connected ! Which they are
Can hear the fuel pump actuate so I dont think its the MFI relay, otherwise the fuel pump wouldn't work?

Any thoughts would be of great help at this point ! ;-)))

Fuel pump only actuates when your cranking, so I doubt you're actually hearing the pump. First gens are notorious for failed capacitors in the ECU. I'd look there.

I know that is what I was referring to hearing it while cranking, yeah I was thinking ecu also, but it still gives out codes, so it is working to some degree ?
