Car won't start fuel pressure is dropping

[jdmfairladyz]

Hey guess first time posting here. I bought a 1997 eclipse gsx and it would not run smooth. I got a p1105, so I replaced the fuel pressure regulator but it still will not run. I have compression and spark , when it was running it was running lean. Now it won't even start up again. I got to 35psi for fuel pressure during cranking and then it just drops. I see no leaks. Please help.

For the cost of a filter id slap one on real quick. Or take yours off and blow through it and see if its clogged up

ok thanks. the fuel filter is not clogged. i was checking for spark and i pulled of all the wires and when i went to plug in my scan tool i got a p0335 code. (crank position sensor) did this code pop up because of the test i ran. the car will not start should i go ahead and replace the cps. i have good fuel pressure.

Hey guess so my car started to run really rough and i got a code to replace the fuel pressure regulator and i did. now i have compression and good fuel pressure. now the car just cranks and will not start up. i plugged in my scan tool and i got a p0335 for the crank position sensor. did this code come on because of the test i ran or is the sensor bad. if so how much trouble is it to replace the sensor my self. help me please thanks.

Have multiple problems post them all in the same thread, more than likely they're related.

Car won't start no spark or fuel injector pulse and p0335 code sould I replace the cps

sounds like a bad crank position sensor. i have experienced a few where the balance shaft belt breaks & takes out the wiring to the crank sensor. the balance shaft belt may also be part of the rough running condition you described
