After driving most of the day yesterday, I came home for a few hours then when I went to start truck it started, barely, got to around 900rpm and died out.
Went to start again sounded like it was going to go, was definitely firing, but wouldn't start.
The timing chain rattle has been occurring at cold starts for about 7500kms, it goes for about 5seconds then goes away.
I have no error codes, truck has ran well for the winter, but a few symptoms I have experienced prior to this no start problem are,
A, During initial start up, the engine will rev from anywhere to 1200-1900 rpm, then normalizes.
B, The idle has been a little rough as of late, not bad at all, but still noticeable low rpm idle dip up to about 100rpm fluctuations.
C. During start up, only very recently and sporadically, I have had to hold the starter for extended period 3-5 seconds for a start up.
Rented a Fuel pressure tester today, plenty of fuel. Pre prime held at 60psi.
I haven't tested spark, but I am sure it's there, I will figure out how to test that tonight and give it a go tmmrw.
I have a compression tester, but last time I tried to get the spark plugs put, I couldn't, last bit of Maintenence (changing plugs) that I have yet to accomplish for this reason.
Also was wondering if it Could it be a cam position sensor? Mine has the fuel line running directly over the nut... and I can't really tell where the clip for the electrical connectors is for this sensor?
