I've been trying for a week to get my car started ! First I wasn't getting oil pressure but it turns out the oil cooler lines were to small and was restricting the oil...so now thats good then I check for spark and I am getting spark at the coil and plugs. So now I hooked up the fuel pressure gauge and turned the key...the pressure builds up to around 40psi then drops fast to 0. Now I know I have at least 1 leaky injector and I buying those this week I don't have any leaks and I've replaced the filter. Would the leaky injector/s cause the car not to start ? Also my fuel pump doesn't sound strong could it be a weak pump..I dunno any suggestions ?

very likely could be a bad fuel pump.

Try swaping the injectors maybe first before going into the pain in the *** of the fuel pump. It is posible to flood a fuel injected car. At start up it is designed to dump fuel down for the initial startup. The leaky injector could be flooding the engine. Do that first since its leaking anyway then work from there.

try starting the car with the pedal to the floor. this will shut off all the injectors if thats a possibility and maybe allow it to get itself started
