I bought a 1988 RV 460ci EFI [for cheap], the PO figured the timing chain skipped a tooth. I tested for fuel and found the high pressure pump was fubar, so replaced it and it fired up. Idle was erratic and vacuum was low @ ~13-15 psi. OK, maybe the chain WAS gone....tore it down and NO, chain is fine. Crap. So now I need help in diagnostics. I pulled the distributor so I could get at the TFI and will test that tonight or tomorrow morning. While the front of the motor is off I plan on replacing the sparkplugs and doing a compression test. There is very little room to work on plugs/wires when the motor is together and the rad is in place.
Is there anything else I should look at?
PS; the unit is 40 miles from home and no parts places close by.
