Engine first start, Fail.
Yesterday I made the first attempt at starting the engine since rebuild. I had put two gallons of 93 octane gas into the tank and the pump runs as it should when turning the key. I had a timer ready to perform the 20 minute cam break in. I was arrogant enough to believe that the engine would simply start when I finally tried it. WRONG. It caught for a few moments then died. And subsequent attempts gave no better of a response. I had turned the engine over with the coil disconnected to build up oil pressure before attempting the start. And thought I may have run the battery down some. Checking it showed 12.56v resting and 11.44 while cranking. I connected a big boat battery with jumper cables but still no start. It turns over and fires a couple times giving of puffs of exhaust, but does not catch and keep running. Pulled a FI hose and checked that I am getting gas, also pulled two plugs and they are wet with gas. I thought I may have flooded it so I put the battery charger on it and put it back in the garage. This morning I tried it again and the result was the same. It fires a couple times then just cranks. Everything is new. Cap and rotor, points condenser plug wires etc. injectors rebuilt buy Witchhunters , static timed when I put in the distributor. All new vacuum hoses, rebuilt MPS (set to 037 specs) ECU is an unknown but it worked when ran last (in ’89) all the wiring was carefully checked when installed Engine build is as follows. EA 1.7 engine built into a 2056 Using the djet FI with 2.0 parts, intake runners, throttle body, air cleaner, etc. HAM heads ported to RS+ and modified for the 2.0 runners Raby 9590 cam Guess I will start with rechecking the timing and go from there. |

Back at it again today.
Pulled the distributor checked that the advance weights were free and moved smoothly. put in the new condenser and rotor. replaced distributor static timed it at the 5 degree mark. Disconnected and plugged all of the vacuum lines to the plenum except the MPS. They were both vacuum hoses to the distributor, cold start valve hose that goes to AAR, Line that tees off and goes to the decal valve and the other line to the decal valve. Turned the key and it started right up, AND again went to 3200 rpm. Set the timing at the 27 deg mark ( it was only a 5-7 degrees off anyways ) Still running at 3200. since the air filter was off and I could access the throttle body I put my hand over the throttle body and the revs faltered a little but stayed up. squeezed the hoses on the plenum to see if there was any change, None. Didn't notice any movement on the stubs from the plenum either. Left it run for about 5 minutes while I did this and then chickened out and shut it down.. Next step is going to be removing the plenum. Damn, this is frustrating. Looks like I will also need new intake runner hoses since I messed these up a little sliding them back on the intake runners to get them off of the plenum, with a big screwdriver. |
