Ran well before storing in a dry shed.
Evaluated the fuel system and installed new: fuel tank fuel level sending unit fuel tank screen fuel filter Cohline 2240 & Gates Barricade fuel hose rebuilt Bosch 3 port fuel pump (4) Standard Motor Products JF67 Injectors Verified the stainless-steel tunnel and engine fuel lines are clear. Applied 12 volts directly to the fuel pump to prime system. Fuel is circulating (can hear the gurgling of the return in the tank). Ignition in the ON position the fuel pump primes (can hear running for 1-2 seconds). Ignition in the START position fuel pump runs (verified with voltmeter, can't hear running due to engine cranking). Ignition in the ON position apply throttle can hear fuel injectors click. Engine will run with starting fluid. Could it be fuel pressure? Fuel pressure regulator go bad from non-use or E10 fuel? (E10 fuel destroyed my Cohline 2134 fuel hose and Bosch fuel pump) Don't know if this could be a factor, sometimes in the START position, nothing, have to return to ON position and retry. Failing ignition switch? What else should I look for? Found a video from May 2017, started after sitting for 5 years. ![]() ![]() |

The injectors click but it is fuel starved.
Fuel pressure spec is 28.5 psi, so bump it up to that pressure. New injectors…next step would be to fire them into jars. If they don’t flow, get them cleaned/serviced. Definitely put a hand vacuum pump on the MPS and pull it down to 18 in/hg to verify that it holds steadyvacuum. |

Manifold pressure sensor not holding vacuum. Pulled vacuum to 18 in/Hg and 4 minutes later was at 0 in/Hg. Will need a rebuild. |
