:tdown:hello all typhoon wont start turn over after new fuel injectors was doing same before new ones installed help

Re: typhhon wont start after new injectors

Have you checked fuel pressure? What made you think it needed new injectors to fix the no start condition? Does it crank? Can you hear the fuel pump turn on with key on, engine off? Modifications to truck? Need more info. Thanks.

Re: typhhon wont start after new injectors

verify that your getting fuel pressure at the rail with the key on/engine off. If not and you don't hear the pump priming then it's most likely the fuel pump relay on teh fire wall or pump itself.

hello yes getting fuel pressure old injectors were having fuel run out of cylinders 5 and 6 wouldnt turn over barely till i pulled plugs guys on here said probably injectors stuck.stock new plugs new fuel pump thanks

Re: typhhon wont start after new injectors

what style injectors stock type or larger.

May need fuel map/tune with larger injectors. Squirting too much fuel into them loading the cylinders up is no good. You may sacrifice your bottom end.

Re: typhhon wont start after new injectors

it has stock accel ones 30# what about fuel regulator would it do this thanks? it tries to turn over but barley thanks.

Re: typhhon wont start after new injectors

problem was at first it would try to start barly then would die when i give gas then got worse and wouldnt start andf barley turn over and gas was leaking out of plugs so i pulled plugs and would turn over great, thanks

Re: typhhon wont start after new injectors

Fuel filter on back wards? Did u hook up a gauge to see how much pressure ur getting or to see if it's bleeding off quicker the normal?

Do you here the pump prime?

Plugs wet?

Re: typhhon wont start after new injectors

Fuel filter is right yes pump is running yes plugs are wet even with plugs out it turns but usuallyhard then cranks no guage on it yet thanks

My advice is remove the fuel pump relay fuse crank
over the engine to burn out the excessive fuel that is in
the intake manifold if it does crank over you know that it was
getting to much fuel did you check if the injectors are hi impedance
just check it with an ohm meter it must read 12 to 15 ohms !!!!

Re: typhhon wont start after new injectors

I already pullled fuse for relay and still wont turn over barely injectors are 150630 accel injectors check ohms what with key on and just touch wires on injectors harness thanks

Stock Fuel Pressure Regulator? I have seen a few go bad.
A way to check: Remove the return hose on the bottom of the Fuel Pressure Regulator and see if it is flowing back to the tank. I have seen them completely blocked off and the fuel pressure go up to over 100 causing all sorts of problems. Just something to check.

Re: typhoon wont start after new injectors

got fuel ? got spark ? got air ? got compression ? have you got a bad battery in the thing ? start with the simple things then move forward . does the tach bounce when cranking ? check fuses ? do you have a check eng. light when ignition is turned to on position ? sorry for the ?? but this will help diagnose your problem .

The injectors ohms check has to be done with the multimeter
on the two pins at the injector you have to remove the injector
plug harness just in case just remove negative battery terminal !!
If your starter cannot crank engine over this can be your problem !!!

Please stop bolding things. Also, don't hit the enter/return keys to wrap the text, IE/Safari/Firefox/Netscape/AOL does this for you. It makes it really hard to discern what you're talking about. Good advice, if presented incorrectly, can get lost in the re-re-rereading.

I agree with Syclone22, does it crank normally if you have the plugs in and the fuel pump relay disconnected? It should still spin fairly smoothly.

Spark? Place a timing light on each plus wire (4" from the plug). If you get a flash, you're making spark. Also make sure the ECM fuses are good.

Fuel? Sounds like yes (if you're saying they come out wet). Did it ever start with the old injectors?

Air? Obstructions?

yes it did start with old injectors but it would die when I tried to give it gas . Then later wouldnt start at all gas was leaking from back plugs.it barelly tries to turn over with fluel relay unhooked yes getting spark from plugs new battery and starter selnoid thks

Re: typhoon wont start after new injectors

Timing and everything else is up to 100%? Fuel pressure set to stock? Any vacuum leaks?

If fuel rail pressure is set at 43 psi with vacuum line off and you have
ignition i think your injectors are staying open this can be caused by
a faulty engine coolant sensor or damage vacuum line at the map
sensor check these first before removing the fuel injectors are the
injectors the same lbs/hr rating ???
