Welcome to Yotatech.

Do you have a FSM? If not, there are some troubleshooting tips there.

Good luck and please update when you find the problem as that helps future users with the same issues.

have you checked that the fuel injectors are getting the signal to fire?
have you checked that the distributor is installed correctly? ...with the rotor pointing at the proper cylinder?

scharp

see i know we have fuel to the filter, but i havent checked yet to see if its at the rail or checked the signal. also we jumped the diagnostic port and got 8 flashes, a pause then 11 flashes, a pause then 2 flashes

What year is the truck?

scharp

its an 87

arizonaguy

do you have compression?????

abecedarian

is the air flow meter hooked up, physically and electrically?
2 and 8 point at the air flow meter, 11 points at the throttle position sensor

scharp

yea we have compression, the air flow meter is hooked up

abecedarian

Have you been working on the engine- rebuilding or replacing it? What work's been done on it recently?

Here's the codes breakdown-
2: air flow meter signal: VC or E2 open; VS-E2 or VC-VS shorted
8: intake air temp sensor: THA open or short
11: neutral safety switch is on, or TPS IDL signal is off when diagnostic terminal is shorted.

here's troubleshooting of the TPS: http://www.4crawler.com/4x4/CheapTricks/TPS/index.shtml

scharp

well this is a standard so it just has a clutch switch and it should start right

abecedarian

the code means the clutch was depressed and the switch was on when the jumper was inserted
OR
the TPS IDL (idle contacts) were not closed when the jumper was inserted

scharp

so your saying that i might not have to pay attention to that code

xzyragon

is it timed right?

is it at TDC 1 when you start it?

abecedarian

scharp- disconnect the battery for a few minutes to clear the codes then put the jumper in and go turn the key to 'on' (don't start it) and see if anything comes up. If it does, then that may be something to worry about.

and yeah, I asked earlier but didn't get an answer and xzraygon brought it back up- have you checked the distributor?

scharp

yea i checked the distributor. but i did some volt testing and the tps fully open is supposed to have 4 - 10 volts and it only and 1.7v i think i found the problem. would that cause it not to start

abecedarian

well... yeah it could.

so, with the #1 cylinder at TDC, both #1 intake and exhaust valves open, the rotor is pointing at approximately 10 o'clock?

scharp

yes everything timing is good. how would the tps cause it not to start?

abecedarian

before we go into that...
you said the TPS tested bad. What terminal tested bad? VCC, VTA, IDL, E2? What was the battery voltage during the tests?

abecedarian

While waiting for that... do you have continuity between E2 and IDL terminals (3rd and 4th from the top) with the TPS installed and the throttle closed?
(those are the ones that will throw the code)
