So decided to go at the car today.
Disconnected the fuel pump relay, cranked the engine and did not start thats normal least we know that works ha.
Reconnected the fuel pump relay, cranked it and it started poorly…..
The preasure gauge showed me the needle was jerking rising up towards normal preasure but did not reach normal preasure engine still poor.
So turned offf engine and preasure droped immeadiatly.
Disconnected the fuel pump relay and cranked engine car started perfect till it shutdown when ran out of fuel..
Reconnected the fuel pump relay and cranked engine engine ran poorly i forget now what the preasure was but i would say it was the same as the first time it
ran poorly untill about 4 or 10 seconds the engine starts to run fine and preasure builds up to normal and then when i turn off engine the preasure drops
immediatly.. So am i wrong by saying my cars gets flooded lads…..
Ya i have checked the omh in the injectors and all is fine i could do the noid test and maybe the leak down test now when i get the kit. Thanks for the reply lads.
Well i didnt have the fuel pump tester connected between the fuel filter and the injectors when testing it. I connected it to the fuel return line
so that would affect my results would it????????.
I would disconnect the LC-1 unit and Heater plug to see how your car will run. If things goes fine connect your Heater plug back in and see how things run for a
while. Im no expert but it might help. Also maybe the two short cuircuits that you had may have done damage to sum other component a posibility like the IAT, when things
heat up like that it acts like a welder to other components…….. Im no expert but eric the car guy advice and others advise would be first preverance to mine.
Ok lads their is another issue that may not be quiet clear to me i have replaced the coolant temp switch with a second hand one and has’nt improved things but
if i plug in the spare one and heat it up with a lighter and start the car it will rev up fine are these two coolant sensors faulty????????????? Also i have a fuel
preasure gauge and do not have the proper fittings yet to connect it to the direct inlet to the injectors but connected it to the fuel return line and checked the
preasure i griped the return line and the preasure held in the injectors but as for not gripping it the preasure droped straight away after shutdown.
Well i took each injector out and had a 12 volt battery with two leads one to the positive and the other to the negative connected to the injector only stricking the
negative every two seconds. Had small amount of petrol in a hand pump connected to the injector holding the preasure with my hand for the spray. Only done
each injector for about 20 seconds test each… Or maybe i should Have sumone else have a look at them with the proper equipment.
I Just tested the injectors and they seem fine no leaks i dont think unless i have to leave them sit for a while but i do know i could nearly put a bet down that when
i put the injectors back and all the parts and dont start the car till the morning, it will start perfect and i have no idea what is wrong. Is their such a thing as too much
preasure in the fuel line cause i find the car runs ok if i release the fuel pump relay or is it a wiring problem??????????????????????????????
Thanks for the reply
No check engine light on, ran on board diagnostics on car and no fault whatsoever.
Tested the resistance of coolant tempiture switch and seems to be fine increases and decrease according to tempiture.
Now not too sure about the injector test i manually took each injector out and cleaned them and tested them with a 12volt batery and spray seems fine although
im no expert!!!! And would’nt have the proper tools just applying hand preasure to the injectors for the spray.
The engine will start first turn but very poorly running. Just barley ticking over untill it gets its barings and runs normal.

Just the fuel Regulator vacuum port disconnect ya i will do that and let you know how i get on. Maybe Dreamer was on about the injectors leaking aswell
that could be causeing the problem……
Ok i have checked the fuel pressure regulator against the video that Dreamer has shown me thanks for the example too and ran the engine for 5 minutes
and no fuel came out. Apparently if i start the car when the coolant tempiture switch is telling the ECM of cold condition its starts first turn but rough
idle and then after 5 or 10 seconds runs fine and wont cut out. Every morning except during the summer when the weather is warm in the mornings and starts up
fine. Thanks for the help so far its great. In the winter it wont start first turn due to freezing tempitures and usually takes a second turn of the key and rough idle
then 5 to 10 seconds cars runs fine………………….
Na this does not have a cold injector its the newer engine or its the 4AFE engines thats more fuel to the injectors their is 4 Injectors but i think that Dreamer and
Eric the Car guy might be on to sumthing about a leaking injector because when i took out the injectors to check them individually i might have misdiagnosed the
problem i watching for the spray and did not know much about them anyways that they might be leaking so im going to have to do this again any easys of
checking my tool are prehistoric cuz i dont have tools……………………………………… thanks guys and love the website its cool out. Forgot to mention that car was
laid up a while too because i could see signs that the car was not used for a long time and the throtle bodys are fine because i cleaned them out……………………………
