I have been driving my project car around now for nine months as I work on the body. It always starts on the first turn of the key. I drove it today and then worked on the body again and it woud not start (I know the engine is jelous right).
I know little about engines so I brought a certified BMW/Mercedes/Audi mechanic over (I know, but I couldn't find a Nissan mechanic) and we did the following
-installed guage to check fuel presaure and it is at 40psi
-pulled and cleaned the plugs
-pulled the rotor and dist cap and cleaned the contacts
-checked and found spard in the distributer and at the plugs
-checked the airflow flap thing and it is working
-checked the relay for the fuel pump and it is ok
-checked the connections at the fuel pump and it gets juice
-checked the injectors and they are getting signal
so what it does is wont start, it ran fine this am parked it then this afternoon it didnt want to start it cranks and fires and sounds like it wants to start but it doesnt
I did get it to start one time after the onset of the issue and it smoked out the exhaust and the mechanic said it smelled rich
when cranking it smells of gas like it gets flooded, he thought the throttle body air unit may have a leak and pulled the hose off to find none
I have another airflow sensor thing he wants to switch out for grins
When it is cranking it turns over and sounds like it is going to fire off and go but never does.
The mechanic cant seem to figure it out, but said it is almost as if the timing if off, which he will check tommorow, but I didnt pull the distributor to mess that up
Any ideas , anyone?
I did have it low on gas and all we had was some race fuel handy and put in a gallon it wouldnt start, then I added five gallons regular unleaded to thin out the rase fuel so it wasnt too rich or high an octane, but that allegedly wont hurt it I was told.
HELP:?:
PS
I have changed the oil, fuel lines, fuel filter, air filter, heater hoses, radiator hoses, and been maintaining it so it is not like it has been neglected. I been doing normal maitenance
