Hi Guys,
Another newbie i'm afraid! And down here in Australia so some bits n bobs might be different for your trucks? but essentially the same car.
I've been reading your threads for a while now as I always seem to get to the bottom of stuff with a few of your pointers. And it seems most of the problems I've come across have been had before and someones fixed it!
Well this isn't a new one either but there were a few things during tear down and putting it all back together that have probably contributed so I thought I might just be better asking a few questions.
Firstly, History. The truck was showing signs of a blown HG about 4 months after buying it. After pulling the head, sure enough! although the a****** had stuffed it full of radweld or something similar to sell it on. This had clogged all the cooling journals in the block so I decided to just get and do the full top and bottom rebuild as the truck had high KM's anyhow. Just a little over 300K in your money.
First issue was one of those tired and should have quit earlier mistakes! Had started removing the alternator but the plug on the back was being a real bitch so decided to come back to it. Only problem was it got late and captain smart arse decided to reconnect the battery to lock the truck up, caused a nice short on the side of the alternator and a bit of smoke and electrical burning. Needless to say I'd blown the fusable link on the battery positive. I found and replaced that thanks to your forum. And have spent time testing relay connections and switches. Somehow all relays and fuses seem to be all ok.
So where I'm at now! Immobiliser is all working. I've got CEL and can read fault codes (only showing engine temp sensor fault). I have power at the EFI connections and at the fuel pump connector. She turns over really strong but won't fire. I've swapped out the fuel pump and changed the connector as it was cooked. Also had all the injectors and fuel rail cleaned and tested professionally. I'm definitely getting fuel as it was weeping from the engine bay filter. A bit of a nip up and that has fixed it. I did a spark test and the spark looked weak so I've tested the coil resistance. Resistance was low on the +and - so I've gone and got another one. Also went with a new head as she's on LPG also, so shes got all new valves etc and cam shims are all well within spec.
So Q1, The coil I've received is about 10mm narrower than the original. All the resistance readings are in spec and i was listed as being for my truck, so in my eyes apart from needing to modify the bracket I should be good with it? Yes/ No? And yes I'll do another spark test tomorrow and check if the plugs are getting wet.
Q2, Could there be another fusable link that has blown somewhere even though it's turning over and the fuel pump is running from the key?
Q3, When the new timing chain arrived it only had one bright link on it. When I had fitted it I turned the crank over twice while it was still on the engine stand and all the marks seemed to line up fine. I'm guessing it's still worth rechecking along with the distributor alignment?
Q4, Due to lack of funds / work commitments etc the truck has sat for 9 months +. Is it possible this could be a dud fuel issue. Have thrown in a jerry can full of fresh premium (as advised by a couple of people I've spoken to) but am I better dropping whats in there and starting again?
Q5, Anything blindingly obvious that I'm missing/ overlooking or could do with checking?
Any help would be appreciated.
Thanks in advance.
Chris
