10 psi is just barely enough to run a TBI motor... i would almost bet that you have a fuel pump going bad... 13 psi... and blocked.. at the fuel filter... close to 25... be sure to replace the fuel filter Orings when you are done.. with new ones.. take the fuel filter off..... stick a clear plastic gallon bottle over the
fuel line from the tank... have someone crank the motor for 10 ...

which engine??? 1994 GMC Sonoma 2WD: 4 Cylinders 4 2.2L SFI OHV 6 Cylinders W 4.3L CPI (found in 17% of 1994 GMC Sonoma 2WD) 6 Cylinders Z 4.3L
TBI (found in 83% of 1994 GMC Sonoma 2WD) i would think that the misfire under load could be... a clogged fuel filter... a fuel pump going bad... the vortec motors are really sensitive to fuel pressure ... and they have been known to cause this ...

i wonder... did you find any
bleeder screws on the motor.. there are some on some models... snip : Remove the bleed valve on the top of the water outlet housing to vent the system, as soon as coolant begins to flow out, install it There is also a bleed valve located on the bypass tube, this valve should not be used to vent the system when refilling it snip it might be also that when you ...

there are a bunch of people with this problem... change the
oil pressure sending switch... use the proper oil pressure sending switch socket to do it.. some stores have tool rentals so you may not have to buy it... the idea is also to clean the area of the threads with brake cleaner first... (Before you take out the old sender) then if you jeep has a coil.. unplug it... with the sender ...

more than likely... the fuel pump is going bad from being run low on gas... since most toyotas have a fuel pump access panel under the back seat... its not that hard to replace it... i take it that the engine is cranking... when you are trying to start it... the engine does turn with the starter motor... some drivability mechanics have a low amp current probe and a DSO (
digital storage ...

positive.. touch the other connector... crank the motor.. if you get pulsing light..???? ...

Matt, I hope you get your money back!! ) I certainly need my money back. My husband passed away suddenly from cardiac arrest in Dec. 2007. My son and
son-in-law wanted to get an engine (badly) in order to finish a 1967 Firebird that my husband was having completely restored. We were all still in shock, and were NOT thinking straight when we ordered the 400 Pontiac Engine from AA Rebuilt...
