I got in touch with Mark, one of the local MB owner, he let me borrow a coolant temperature sensor, an EZL and an ignition coil to trouble shoot.
I tried the sensor with no changes. Before I disconnected more cables to replace the EZL, I followed his advice and bought some starting fluid and tried to start the vehicle. The vehicle started and died as usual. I tried it a couple of more times and on the third time, the car did start and, even though it died...it lasted a few more seconds before it died. Based on that fact, I reviewed my notes to see what I had done in the past two months to the car that had to do with fuel. I then remember changing the EHA with a used one I had in my spare parts. I keep the old EHA...just in case. I changed the EHA and the car started right away and keep on running. I adjusted the duty cycle to around 55% and I drove around the neighborhood with no ill effects. Like I said before, I think I had two different problems and I hope between the EHA and the new CPS, both problems go away.
I know the EHA is part of the ignition/fuel regulating system but, preventing the car from starting...? Has anybody experienced this before...?
