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 from a little vacation to OBX, my new intake tubes and gaskets were in the mail when I came home.
Put it all back together with the plenum repaired with JB weld I expected the best. Well, it started right up, and again went to 3000+ (IMG:style_emoticons/default/sad.gif) But this time I let it run to finish the cam brake in. Set the timer and while it was running I started pulling and plugging vacuum lines again. most had No effect. but when I pulled and plugged the line from the throttle body to the dizzy the rpms increased so I plugged that one back on. Then I tried spraying starting ether around the connections and noticed a little stumble at the throttle body, I put the new gasket on dry so maybe that was leaking a little. also sprayed around the intake runnners to the head and got a definite stumble on the driver side. I just had that off. maybe the gasket didn't settle right there, Its hard to get to the bottom bolt in the middle. Also when I depressed the clutch the rpms would go up considerably, So I guess the clutch is releasing, at least. After 15 min I shut it off and when I went to start it again.... NO buzz from the fuel pump.. (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/ar15.gif) So of course it won't start now. Damn this sucks, you would think that I stole a backpack full of rocks from Pele. Now track down the fuel pump problem. Checked the easy things first. fuse on relay plate is good and power is there. also switched the relays but fuel pump still doesn't run. Where does the power come from that runs the pump for a few seconds ?? My fuel pump is front mounted and the wires run through the cabin, so I think I will put a couple spade connecters in line there and run power to the fuel pump to see if it will run. better than pulling the tank. Then I get to remove the intake system again. I need a vacation from this thing... |
