    60psi is pretty low compression. How long have you been running it without an air filter?

        get a multimeter and check the crank sensor, cam sensor, and make sure you are getting spark. Also check all your sensor and power connections to make sure everything it tight and nothing is loose.

        you can also check the fuel pump by pulling the relay and jumping the 87 port to the 30 port with a piece of wire. Car does not have to be on. If the fuel pump is good, you will hear it running when you jump terminals.

        Search on here and m42club.com and start reading.

        I am having the same issue. :( not solved yet.
