Driving my Daytona to church yesterday, I noticed a bit of intermittant loss of power at times, particularly at higher throttle input. I ran a few errands afterward, and the problem got immensely worse, with the engine bogging down while trying to start moving through intersections. I stopped and disconnected my CTS, as I know that it is bad (I've ordered a new one from rock auto already), to see if it would solve the problem. Noticed that the temperature sensor on the throttle body was disconnected at that point, so I reconnected it as well. Made it to one more store with some serious heasitation and bogging, then eventually had to pull into a parking lot as it was obvious that I wouldn't be getting any further, and the engine eventually stalled out.
My current symptoms:
With CTS connected, engine will crank but never "catch" or fire at all (an issue I've been having at certain engine temperatures, and the reason why I disconected my CTS to try to solve the issue)
With CTS disconnected, if I let the fuel pump run its priming cycle twice, the engine will start, but then die after 5 seconds, or the first time I open the throttle.
I'm assuming this is a fuel delivery issue, either a clogged filter or bad pump. The pump did not sound like its normal self yesterday, but has a bit more of a labored growl to it. It runs for a few seconds when the key is turned as well, not the slower half to one second cycle that it runs when the system is pressurized normally.
Does this indeed sound like a fuel issue? Codes are 15 (speed sensor, a new one for me), 22 (CTS, consistent with my bad CTS and/or me disconnecting it), and 23 (Air charge temp sensor, consistent with it having been unplugged).
Unfortunately, I am out of town for work through Friday, and then next week Monday through Friday. Fortunately, they get me a rental car when I travel, but unfortunately, this means I need to plan my diagnosis for a limited amount of time next weekend, and the repair for the following weekend. This is my plan of attack:
-Replace the CTS this weekend
-Check for 12 volts at the fuel pump - determine if issue is electrical or not
-Test fuel pressure at several points in the system to determine if the issue is pump, filter or regulator
-Possibly replace the fuel pump (if determined to be bad) the following weekend.
If this turns out to be the pump, how bad is the job? I'm in Minnesota, and the the car is currently sitting in my front yard in about three inches of slushy snow (couldn't push it very far out of the way), and unfortunately has about 3/4 of a tank full of gas. Should I expect to buy new straps for the tank as well, since they are probably rusty, and can the old pump mounting hardware be reused?
Sorry for the long message, I'm trying to plan out this repair in advance since my actual repair time is so limited. As always, thanks in advance for any and all suggestions!
