| 1985 Pontiac Fiero SE 2.5L Cuts out, Stall VIN: 1G2PF37R3F When I started with the vehicle it w/n start & had a code 33. I checked spark & fuel, no spark, fuel coming from injector. I checked cap, rotor & coil (all ok). I checked fuel pressure (8psi but I question my gauge due to hardly ever using the low pressure... Trouble codes: 33 (MAP sensor would not start), 44 (Lean), 42 (Electronic spark timing) |
