[quote=”bwebb” post=36517]Ya there is plently of fuel psi. and the car runs fine, just when i start it i need to use starter fluid to get it going.

keeping in mind that the battary sucks [and every time i go to start it the car needs jumped] could this battery be so dead that it wont creat enugh power for the spark plugs to ignite gas but it will ignite the starter fluid. then the altinators power takes over and is suficent enugh to power the spark plugs more so they can now ignite gas as well. dose this sound something that could happen at all? ive only been a mechanic for a year now so im still learning these things[/quote]

I would be hard pressed to think so… If you will feel this could be the issue. Get a spark tester and look for weak fire (You should see blue sparks) Orgenish fire indicates weak fire. (If theres a enf power to crank the engine theres enf to fire the plugs) You could have some bad plugs/wires.

Try cycling your keep… Turn your key on for 30 secs but do not crank then off for 30 then on again- Repeat a few times. (Make sure you turn the key fully on and listion for the fuel pump)

I recently work on a 09 mustang that was having to same issue… We looked at everything… Just by luck I noticed some one had messed with the throttle screw…
They had tryed to turn the idl up… I reset the screw and the issue was gone…
New cars – Timing and Idles is controled with the Ecm/Pcm on board computer messing with the dizzy or idle can cause many issues…

Other things to check would be (TPS – Air Idle Controls – Air filters – Leaky intake or plenum. Lose hoses. (Check your air filter hoses/lines) Sometime these can get cracks in them a cause issues)

Setting here thinking about your comment – Sometime else that could be happening is (Maybe you are not getting enf power to the fuel pump/relay) This would make more since. If you battery’s weak – Cranking takes alote or power – then powering the computer/relays and all the other goodies – You could be getting weak power to the fuel pump) You may hear the pump engage but when the engine starts cranking your not maintaining the right amount of power…

Hope iv helped.

Im sure one of the top guys like – Eric – dreamer – Mopar – will be popping in to help.

Hang tight bro.. We will get you threw this.

We need – Make – model – year – so on. Also any mods made to the engine.

Wrong… Not even near to being true.
Iv seen many engines pass fuel psi test and there steal be issues at the filter.
I can go into detail if you like.

your mastery of the english language as well as your innate ability to eliminate all potential diagnosis is quite compelling; however, I will have to yield to you and say that you are indeed correct. that is why it is important to perform a “fuel volume” test. this will indicate any reduction in fuel flow that might be a result of a bad fuel filter, dirty injectors, faulty fuel pressure regulator, vacuum leak, low voltage, high resistance or any other possible causes of reduced fuel flow. in general, a fuel volume test should indicate 20oz of fuel flow from the fuel rail schrader valve within 15 seconds. since you have previously stated that you’ve already tested fuel pressure as well as fuel flow and you have said they were both within spec, then there is no need to look at the fuel filter.

Maybe you should have got a auto repair manual instead of the 8ball?

I prefer to use AllData; not only is the information updated regularly as opposed to a repair manual, the subscription cost alone is probably more than what you make on a monthly basis.

have a nice day. :stick:

If you read what I wrote…. I have seen many engines pass fuel pressure test and steal have issues and the filter….

Meaning… The filter may be allowing fuel to pass…. Over time the inside of the fuel filter can decay and start to brake down… http://www.cherokeeforum.com/f2/inside-old-fuel-filter-pics-28911/
Just like whats happen to this guy.
The filter can start to brake down inside and allowing fuel to flow and bits and peaces of the filter its self to pass to the ejectors or carb.

Im sorry my mastery of the English language bothers you..
Now I myself have never went to school a day in my life… I had a dieing mother and 6 brothers and sisters to take care of let alone my self… Knowing these facts – and the fact that Im self taught (I feeling im damn good and I do not need your approval let alone anyone else s)

Maybe you need be the one to worry ABOUT YOUR SELF…..
READ WHAT I WROTE…

Wrong… Not even near to being true.

I can go into detail if you like. ISSUES CAN VARY MY FRIEND.

By all means believe what you want….

A filter is around 10 to 30$ for most cars.
A ejector is around 75$+ X 4 at least for a engine…
Most fuel filter take 10 mins or so to change.
Most ejectors can take hours to change…’

Do the math a then do the work and tell me how its does….

O and dont forget… You changed the ejectors but not the filter —-guess what your gonna kill a brand new set of ejectors for your self or some else….
All because you dont know what your talking about…

I know my ejectors are 79.99$+ -If I spend over 100 let alone 600$ im changing the filter.

My point is….Its 15$ filter -change it. Things happen for a reason…

O BTW… Wanna keep try to belittle me – Feel free to go right ahead and do so. You will lose.
