Won't start - No codes
I'll try to keep this as short winded as possible.
Driving home late Saturday night about 45 minute return from the city, it's miserable, heavy rain, windy, just about 7-8 km's from home, sitting at stop light. Light turns green, hit the gas and my first impression is my tires are spinning on the white lines and then grab pavement, so kind of that sudden hook up at the rear end, only seconds later I come to realize that's not the case and the truck has gone into full epileptic seizure mode, and its surging like its running out of gas. Again as I make my way over to the outside curb lane, I know its not out of fuel, and it hasn't died so I continue driving it to see if I can figure out what the hell is going on. So I can continue to drive it but the tack needle is consistently bouncing from 1000-1500 RPM... wtf???
So I won't seem to make power or get up past 40 kmh, the more load, the more violent and frequent the surges. And by surges I mean it's like someone's flicking the power switch on and off. I also notice that the transmission is shift really hard (not sure between what gears exactly) but it's almost like it doesn't know what gear it wants to go into, and the torque from each shift is giving me that old familiar belt squeal 'type' sound that I no longer believe is the idler bearing. Although this action is somewhat less frequent in it's cycle than the power surges, but twice as disheartening.
I pull over, idles fine... shut her down and pop the hood. Fire it back up and have a listen, nothing glaring, it started fine and idles fine (scratches head)
But, it isn't fine. I limped her home at about 40 kmh max, I noticed that cruising or rolling no load, the surging lessens or basically stops, but as I drive an incline or increase the load it starts back up. Also a point to make is that no engine light has come on.
Next morning, plug in the OBDII scanner, and no codes!!!
It also won't start at all now. Turns over fine, but won't flash up at all.
My first impression is it could be the fuel pump, and after reading a few threads on here, there are definitely some characteristics to support that theory. I can't really tell if I'm hearing the pump prime or not when I turn the key to ignition. But not getting a code for a faulty fuel pump seems a little suspicious.
So, I'm looking for some additional thoughts or suggestions on what to look for.
Going to check for fuel pressure at the injectors when I get home to see if I can isolate it to the fuel pump... or not!
My next worst fear is that it's transmission related, or possibly the ECU
Anybody have these same symptoms, and narrow it down?
Thank you all in advance for your input
