Hello everyone my megasquirt 1 doesn't seem to be working correctly. Ok on tuner studio one gauge I have set it to engine vacuum. When the car is cranking over theres no movement, when I get it running (and boy does it struggle to run) the gauge just sits at 0. I've got a new vac line and nothing.... I've even connected it to a syringe and true to make vacuum from that and still nothing :/. So if I set tunerstudio to 'engine constraints ' and set map type to 115kpa it runs but rich and like crap. If I set it to 250kpa (it has a mx4250ap) map setting. It refuses to start. So evidence looks like a faulty map sensor but are they and other things that I could have missed?
Also it looks like the transistor for the fuel pump has blown. Does anyone know which transistor it is?


It's a mx5 mk1 with a ms1pnp with a v3.57 board
Thanks in advance!

Please attach a copy of your MSQ file and a data log of an attempted start.

Also, note that the MSPNP Gen 1 used a 4 bar MAP sensor for the 1994-1997 models.
