How do i release the fuel pressure so from the system if i cannot get the vehicle started to do it by the book? I need to change out my fuel filter and continue to trouble shoot my car to find out why it wont start. It cranks over and i can also smell the fuel from the system flooding. I unflood the car and its the same thing over and over. There were a couple of times that it tried to crank over due to me giving it gas. I dont think that its the fuel pump or the filter. The fuel pump is new and I dont think its the filter due to the smell of gas whenever i attempt to start the car. I'm out of suggestions as to what is keeping my car from starting.

I think you're right, it's not the filter. If that was the case, you would have an absence of fuel.



What unflood prodedure are you using? Have you pulled the plugs yet?



It just sounds extremely flooded to me. Crank it with the plugs out to clear the excess fuel, clean the plugs good and maybe even a tad bit of oil in each chamber to help restore compression. When you get everything ready for startup, keep your foot to the firewall until it fires off.



As far as your initial question goes, I just crack a line at the engine. Just try to keep the junction wrapped in rags so the fuel doesn't spray everywhere. Not a bad idea to keep your eyes closed at that moment also.



Cheers

alright. this is what happened... i pulled the lower plugs and cranked it to remove the excess fuel. then i put oil in the holes where the plugs go. i reinstalled the plugs, put the fuse back in the car, jumped inside, held the pedal to the floor then i cranked the engine. i got no results in starting the car but i did recieve a loud backfire as if someone stuck a fire cracker in the car. whats the deal? i'm completely lost now.

Hmm, backfire. Well some kind of combustion is going on in there anyway.



Did you get a lot of fuel out of the plug holes?



I forgot to mention that the engine should be rotated a couple of times by hand after the oil is put in, and to only use a dab (~2 - 5mL, about a capfull).



Have you checked your plugs after this recent attempt? Maybe they got oil-fouled if the hand-cranking wasn't done.



Also, with no mention of whether it was running well before or notes on timing, I would say you should doublecheck your timing. Out of time cars will backfire a lot of times.

How do i rotate the engine by hand? i'm new to the rotary game ya know. I would love to get this car up and running. I guess i'll clean the plugs and check the holes to make sure the engine not flooded again. I doubt that its flooded again cause i dont smell the fuel like before. But ever since i put the oil in there, its not willing to make an attempt to start. It cranks but thats about as far as it will go. I have to charge the brand new battery i got for it now. Damn, i hate this!!! lol

MAKE SURE the timing is set properly and you have a SOLID GROUND for the lead coil and engine block.

have you tried pulling the egi fuse under the hood and cranking the motor a few times, then putting the fuse back and try starting it. By unplugging the egi fuse you turn off the fuel pump allowing you to clear the combustion chambers.
