I spend tons of time and money on the ******* thing and still it dont work. Ok so I am gonna start another thread about the pos problem. Ok so i just got my fuel injectors cleaned, new fuel filter, fd fuel pump, and still my engine wont get fuel. Everytime it gets to operating temp it gets no fuel and wants to die as soon as I hit the gas peddle. Rpms wont climp I hit the gas and it just sputters and pops. Ive regrouned my engine ie tranne starter misc other grounds, redid all vac lines and still no progress. I cant take it around the block without this ******* problem happening, please please please someone help me, or I am going to sell this ******* thing. I cant take it anymore.

 

are your spark plug wires in the right sockets? is the timing off? how do you know it's not getting fuel?

also, check your injector wiring.

 

I have an autometer A/F gauge(I know they arent very accurate), its showing my car is runnig real lean at idle and when i hit the gas. Its only when the engine gets warm, so i dont think spark would stop when its gets warm, and it was just timed in the other day.

 

mass air sensor?

 

I tested the Maf with the specs from the FSM with my multimeter and it seemsed to check out.

hmmm, bad ecu maybe???

id take out the injectors and rig them up like it says in the fsm, make sure they are all firing.

I'm not sure how critical the MAP sensor is, but you may try testing that out too.

 

Build a little LED light trouble code reader & check for any trouble codes the ECU is throwing. You'll want to run the wires up so you can see the LEDs blinking while the car is running, but I'm willing to bet you'll find the ECU is very unhappy about some particular sensor.

I second on the ECU. A bad ECU will do the same thing you are speaking of.

 

i have one for sale if it is the ECU
i bought an extra one and ended up not needing it

 

I have built a checker lamp, not throwing any codes.. Ima have to try and swap my ECU before buying one, i dont want to go buying one when its no needed like you did.

 

lol i dont mean to laugh but u made me laugh so hard in ur first post. Ive been there before man you'll figure it out dont worry. Im still worried everytime i start my car cuz it seems theres a new problem every time i get in it lol.

 

i had the same problem

I unplugged the Air temp sensor.. the car runs like a champ... (found the solution totally by accident long story I doubt u'll wanna hear it)

if this fixes ur long headache of a problem... a paypal donation would be much appreciated for my out of the blue ingenious solution

 

check the plugs , get a steady idle and then check timing. and you ecu might be bad. andi read that you have ngk platinums???,, i could be wrong but those arent what Mazda recomends right?? if so try going back to the Ngk 7 and 9 plugs.

 

the Bureq7 and 9 are both available in conventional copper or platinum. Platinum is specified for the FD engine for extra life.

That would have absolutly nothing what so ever to do running and in factr would probably give you an extra .5 mile to the gallon and an extra 5K-10K mile life to the plugs.

 

Sure does not sound like fuel problem to me... if you jumper the fuel diagnostic plug does the problem go away??? This is a swap right???> You did reverse the fuel lines right???

And don't start more/multiple threads on the same problem on the same car.

 

Dude chill, got you guys are so blunt here, i just copy and pasted this thread form nopistons to see if you could help me. So dont worry, there are no multiple threads
