Hello, my name is Jon and I am new to this forum or any forum for that matter. I came here because I really need help. I have a 1971 914 1.7L with original paint and original fuel injection. I purchased the car in 1998 while in CA in the USMC, used the car daily until 2002 when I was discharged and parked the car in a barn MI till 2018. I just started working on the car and have replaced the plugs, wires, cap, rotor, points, condenser, coil, fuel filter, fuel, fuel pump, oil, oil filter, and fuel injectors. I checked the timing by setting #1 to TDC and used the mark on the distributor aligned with the rotor. I set the points to .016 and adjusted the fuel pressure to 28 PSI.
My problem is that the car just won't start. There is good spark at every cylinder. while cranking the fuel pump holds 28 PSI attempts to fire for about a 1/2 second and then nothing. But if I pump the the pedal while starting it will kind of stay running but barely, the fuel pressure will drop, and it will backfire through the manifold. I hate to sound desperate because this whole thing is my fault for waiting so long but my daughter is a senior on homecoming court and said if that ever happened she wanted to parade in my porsche. Well that day actually came Friday 9/21/18! and now I am scrambling. I procrastinated way to long on this car. Please help if you can. I would appreciate it. Jon |

Next stop is Injectors, do not unhook them, just remove one at a time and look at the spray they create when you crank the engine. Remove the Ignition coil wire first. Have them spray into a bottle- baby food jar or similar. Sound like they may be plugged from the gas left in them. If they are not spraying (mist) they will need cleaning and/or rebuilding and/or replacement. I know you mentioned 'replaced' however, I would check them.

I have not tried that because I assumed since they were brand new as well that they would just work as they should. I will try that tonight. To be clear all of this sounds like a fuel problem to you?
