1993 22re 4x4 truck

I’ve been reading as many of the threads as I can, but after trying all the tests I found, it’s still not working:

-Fuel pressure is good
-ECU main relay is good
-Spark is good
-fuel is new
-fuel pump works both jumpered and with the MAF gate depressed
-no fuses blown

-throwing codes 7 and 11 (blinks fast 7 times, waits, then blinks fast 11 times).

If anyone has any thoughts, they’d be much appreciated. At this point I’m going to have to chase individual wires 🤢🤢

4 Or 22
—WATER TEMPERATURE SENSOR SIGNAL--OPEN OR SHORT IN WATER TEMP. SENSOR SIGNAL
--WATER TEMPERATURE SENSOR CIRCUIT
—WATER TEMPERATURE SENSOR
--ECU

11
LOSS OF POWER SUPPLY TO ECU
--IGNITION SWITCH/CIRCUIT
--MAIN RELAY/CIRCUIT
--ECU

If it runs on starting fluid but not otherwise wise, you have an injector or fuel issue.
Typically if you have spark, 99% of the time you have pulse as well.
Verify injector voltage and pulse.

I had an 86 that did this years ago . Turned out the spark plugs had worn out. They would still fire but the gap was so wide that causing a voltage drop to the ecu. Swapped in new plugs, problem solved. Might be worth a shot.
