Default 95 C4 won't start

Good Morning all Happy Friday,

Need some help. My C4 won't start after being park for a month or so. Check for spark, gas pressure ( 38 PSI ), I notice when I tap on the Mass air flow senor it starts but with a big misfire and turns off after seconds of being on. I pick up a new mass air flow senor from Advance Auto part and put it in. Same thing now. Still I tap on the Mass air flow senor and it starts with a nasty miss fire and after being on for a few seconds it turns off. No check engine light on so it's not like i could check for codes. Unless there is a different way.. not sure. Please help losing the few hairs i have left.

That's an odd symptom. How consistently will it start while tapping the MAF? Is it still hit and miss? I wonder if the wiring adjacent to the MAF has rubbed through its insulation, or the connector or the MAF is losing contact. Have you tried starting with the MAF unplugged entirely?
