Out of nowhere, my 85 C4 became a no-start. I tinkered for a while before I ran across a grumpyvette post from another forum that led me to the oil pressure switch.
I jumped the connector and the car started right up. Satisfied that I had isolated my problem, I happily purchased a new oil pressure switch. The new oil pressure switch would not start the fuel pump and I am still jumping the connector to operate the vehicle. Suspecting an obstruction, I removed the switch, gauge, and the tree that held them. I cleaned and inspected everything and reassembled. The car actually started 4 times afterward with some extensive cranking. It didn't last though and I am jumping the connector and bypassing the oil switch again. The readout on my dash during cranking reads 0-3 psi and I believe 4 is required.
Any thoughts on why my pressure is so low and how I can increase it?
