Hi everyone, currently t/s an issue with my 2v.
Built 2v 4.6 Vortech S/C downsized pulley pushing 18 psi
Fuel: 2 Ford GT pumps lined to two FPDM supplied by BAP with the wire upgrade.
Has driven fine for about a year since the finish of the build and tune. Last weekend went on a 100 mile ish drive and parked it till the next weekend.
Drove it to work one day and the car died on me. Found one of the connectors going from the relay to the BAP burned up. Replaced the connector and drove it home. The next day I realized I couldn't go WOT past 4000 rpm without it stuttering and backfiring.
Attempts to fix so far:
Cleaned MAF and Air filter, replaced Fuel filter, checked voltages on BAP(17+ volts), checked voltages to fuel pumps(17+ volts).
Planning on replacing o2 sensors next.
Interpretation of graphs: Graphs show a clear decline in fuel pressure in regards to rpm increasing. Looking for more suggestions and thoughts.
I just read these two links and I am going to check the lines for any smell of gas. It looks like replacing the FRPS will be a safe bet all around. I will also make sure to zip tie all my vacuum line connections.
