We recently drove up to the grid and parked, to go out for the first race of the new SCCA year. At two minutes, they blew the whistle, and the same car that we just drove up to our spot, would not start. No way, no how. The tendency is to blame the ECU right away, especially with these cars. But the folks up a Schwanke say they rarely if ever see one go bad. At lease not with out a good reason (attaching a welder ground for instance) It's real simple, you have to have spark, compression, and gas. In our case, the fuel pump was not priming the system, and there was no go juice, up at the inspection port we installed, on the engine fuel rail. After tracing the dual fuel pump circuit back, we found a slightly unexpected burnt (to a chrisp) four prong wire connector, which kind of ruined the day, and the weekend. Allstar makes a replacement OEM style four prong unit, PN # ALL76269, rated at 20 amps. Our very small packet arrived in a very large box, with a couple of air bags, to reduce the chance of damage (?).
At any rate, we were glad to pay the $13.50 in shipping for this $3.75 shipment, to get after fixing the problem. Make sure you order extra individual male and female connectors, because there is a reason they sell them seperately. We ended up building a whole new harness, on the switch side of the system. There was very little extra wire to work with anyway, so we made sure it will be easier to deal with, in the future. The LS-1 burped to life at the frst spin of the Tilton, and we are back in business. See the seperate blog, about the time the pump connection vibrated loose. These cars are fun, cheap, but somedays, an electrical challenge.
