Hello Carpros :)
I have been trying for a week or so to start my 96 nissan maxima in which sometimes it would and other times it would not? A check engine code stated that I need a knock sensor, crank position sensor in which I replaced KS and both crank sensor, I replaced Maf, TPSensor, coolant temp sensor, fuel pump, spark plugs (NGK-R), I cleaned the IACV, removed and EGR tube due to clogged carbon deposit. Also replaced the intake gasket? I clean the Throttle Body. It will turn over but will not start. I can say that it start a few times in attempting to start the car within the last week or so. I recheck the spark plugs for gaps and carbon deposits as well.
I tested the voltage run to and from the computer for the following parts, TPS, MAF. In which it tested fine?

When I did get the car started it would not Rev pass 2800 rpm no matter how hard I press the gas pedal? Which it tried to bog down like a lack or fuel or something? At this point I dont know what else to try

If you can help I really appreciate it so much and input suggestions would be greatly appreciated. Thanks Joseph

I would suggest starting with a test of the engine compression. The timing chain could have skipped.

Thanks I had the timing chain checked but I was told that it is still aligned.

Will bad coils stop a car from starting if so how many it takes to be fault in order to prevent a car from starting? If so How can they be tested? Thanks JC

It first start by hard to start mostly when it was cold recently. Never really had any problems starting it prior to that time. Then shortly after that time sometimes it would start and ran fine and then sometimes I would get in it to start and it would be hard to start and when I got it started as I stated it would not rev over 2800 rpm like it wanted to bog down no matter how hard I press the gas pedal. Like it was in a limp or safe mode? Do you think the computer could be bad?

I was also told to check the CAT / 02 sensor. I was to as for as the Cat - get the engine hot and look under the car and see if the CAT is red, check and see if I smell a egg like smell- touch the tail pipe to see if it is hot. With all that being said my car had none of those symptons? The tail pipe exhaust had black sut in it like it was running too lean or rich?

I think if I read the check engine codes correctly the codes I read were as followed
po0505?
Po4147?

I had some code about a iacv and egr I think?

Thanks JC

Will a bad CAT, o2 sensor, bad iacv, egr valve prevent a car from cranking.

How like you would buy a fault crank position sensor? Also when JC

The description seems to point to low fuel pressure rather than anything else.
