Finished the last of the installation steps on Wednesday afternoon. On Thursday morning, I got the Elmscan software loaded onto my laptop. This required a big download from the Scantool website, since my laptop doesn't have a CD drive, which would be required to load the software from the supplied disk. After getting the software ready, I took the laptop out to the vanagon and plugged into the ECU port. The Elmscan failed to connect to the computer. After some fooling around, I opened a ticket with Bostig, and ran through a couple of checks suggested by Jim. He asked me to double-check the custom chip installation in the OEM computer, paying attention to whether the contact pins on the Ford circuit board were really clean. Turned out I'd missed several, which were still coated with the plastic barrier. So, I re-cleaned the board and reinstalled the chip. Now everything worked, the Elmscan connected and I was ready for the test start. I double-checked all connections, topped off the coolant, verified the oil, pulled out the fire extinguisher, and turned the key.
Nothing.
The connection to the starter is straight from the key to the solenoid. I confirmed that 12v showed up at the solenoid connector, then realized that I'd plugged the starting connector to the wrong spade lug on the solenoid (there are three - take your pick). After that was fixed, I turned the key again, and the engine cranked healthily.
Nothing.
So, I'm now troubleshooting the no-start issue. We'll see what happens next.
Bummer about the no start, is the fuel pump hooked up correctly? Maybe the injectors are stuck, The is a procedure to unstick them. No clamps on the fuel line? I did that once.
ReplyDeleteAlso the recommended procedure is to turn on the key, but don't crank it, and let the ecu program itself and the engine.
